SK-5 is the Japanese equivalent of American 1080, a high carbon steel with carbon between 0.75%-0.85% and 0.60%-0.90% manganese. As quenched, it has a hardness near Rc 65 and produces a mixture of carbon rich martensite with some small un-dissolved carbides. The excess carbide increases abrasion resistance and allows the steel to achieve an ideal balance of very good blade toughness with superior edge holding ability.

steel is right on the border between a medium and a high carbon steel, with a carbon content between 0.50%-0.60% and with manganese between 0.60%-0.90% as the only other component. The carbon content and lean alloy make this a shallow hardening steel with a quenched hardness between Rc 60-64 depending on exact carbon content.

Almost all steam boilers are constructed of carbon steel, which rusts if exposed to oxygen and moisture The following steps will minimize this problem. (Please observe "shock & burn warnings."): The boiler's blowdown valve must be safely piped in accordance with state and local codes. Ensure that safe discharge is provided for 100 PSIG and 338 degrees F. Turn the boiler off and allow the pressure to drop to 5 psig. Open the blowdown valve for ten seconds, then close.

Yes. We have been overhauling steel brakes since 1984. We were also one of the first to overhaul carbon brakes for several major airlines.

Surface discoloration is normal for carbon steel knives and doesn't necessarily affect the performance of the knives but unsightly stains can easily be removed with a "rust eraser" (offered by Korin Trading) or with the flat side of a wine cork.

We make Surgical Blades in both Carbon Steel and Stainless Steel. The chemical compositions are given below :-

Buna comes standard with carbon steel & Viton comes standard with stainless steel. Click here for o-ring size chart. (Requires Acrobat Reader)

We recommend stainless wok. The reason is ease of maintenance. Iorn wok is only better than stainless when the stove is not powerful enough. Since our stove provides powerful heat, there is no concern in heat transfer to stainless wok. You do not worry about getting rusty if you use stainless. we carefully label our stoves, they are for outdoor uses because of their high power flames. We do not recommend people to use them inside a home.

While carbon taxes will need to be very high to create the required price incentives, they will need to be phased in to give individuals and businesses the opportunity to adjust. There is no magic formula or right number, but a tax that grows at an annual rate equivalent to 5-10% of the ???baseline??? cost of fossil fuels probably offers a viable combination of meaningful incentive and opportunity for adaptation.

Many types of activities can generate carbon offsets. However, not all projects result in credible reductions in greenhouse gases and some cause other environmental and socio-economical problems. High quality offset projects can reduce emissions while providing sustainability benefits.

It depends on your individual preference. Steel is a stronger, harder material increasing its long-term durability. Aluminum is a softer material, which flexes more under tension, but is lighter in weight allowing for easier transport. The latest technology -- carbon fiber - offers the best combination of strength with the lightest weight material on the market today. Sports Imports offers all three: carbon fiber, steel and aluminum.

All seamless precision steel tubes used as pressure lines for hydraulic and pneumatic purposes. Search over www.google.com equivalents for DIN 2445/2, EN 10204.

mild carbon steel has less carbon in the material than 1025 and 1030 mild carbon steels common in forged golf clubs. As the carbon levels increase in the metal, it becomes harder. By using 1020 mild carbon steel in the J33 iron sets as well as J33 wedges, our engineers have developed a golf club that feels softer at impact and generates an amazing feel. Bridgestone Golf accessories should arrive into our Bridgestone Golf dealers beginning April 1, 2005.

Nut thickness standards have been drawn up on the basis that the bolt will always sustain tensile fracture before the nut will strip. If the bolt breaks on tightening, it is obvious that a replacement is required. Thread stripping tends to be gradual in nature. If the thread stripping mode can occur, assemblies may enter into service which are partially failed, this may have disastrous consequences.

Carbon Monoxide (CO) is a toxic colorless, odorless, and tasteless gas. It is produced as a product of incomplete combustion of fuels.

Carbon is an extremely porous material that attracts and holds a wide range of harmful contaminants. Activated carbon is carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules.

Our Carpenter Technology 465 alloy can reach HRC 60. By comparison, carbon steel can reach HRC 62. The difference is about 3%.

We have been making knives in the USA out of our exclusive Carbon V steel since 1987. For the past two years, we have done all in our power to support the factory making Carbon V knives for us, but they have continued a downward spiral and are now in a very severe business and financial crisis and have lost almost their entire workforce.

Usually less than twenty autoclave cycles. Beyond this the chrome plating will begin to flake off and pitting of the surface will begin-with ferrous contamination of the process beginning.

With high surface area carbon black pigments, the particles that require stabilising are very small, so usually a polymeric dispersant can help to do this and thus increase the intensity or ‘jetness’ of the coating. well as using a specific dispersant, the dispersion time can also be critical, with carbon black pigments requiring longer dispersion times than organic or inorganic pigments.

No only tungsten carbide (TC) blades are available for the Nova tip. Tungsten carbide gives longer life when compared to HSS tools. (Answered by Neil McMillan)

Answer: Yes. Stainless steel has excellent properties at both extremes of the temperature scale. Stainless steel can be used down to liquid nitrogen temperatures and up to about 1800° F.

High speed steel should be used for shorter runs of parts made of non-ferrous materials and applications where machining conditions restrict the use of harder, more brittle tool substrates. Solid Carbide is most cost effective to use in smaller tools up to about 3/8" diameter in longer production runs. Depending on the carbide grade, solid carbide can be used for both steel and non-ferrous applications. Carbide tipped tools should be used for long production runs.

Constant exposure to temperatures below 390>?P?F (200>?P?C) is a perfectly acceptable environment for hot-dip galvanized steel. Good performance can also be obtained when hot-dip galvanized steel is exposed to temperatures above 390>?P?F (200>?P?C) on an intermittent basis.

It is a generally accepted engineering principal that tools, which are cast from the proper materials, can be optimally designed to reduce total weight and maximize strength. Cast steel alloy components do not have internal directional stresses that are inherent in fabricated weldments.

Charpy Impact Test at Minus 4deg F for set of 3 specimens (including Machining charges) = US $ 30 per set We will need 3 specimens of about 15 x 15 x 75mm. please inform us size ( dia / thickness) of your material so that we can guide you how to take out the sample.

We would need samples from both good and affected portions of the tubes with a minimum of 2 feet in length. Also take care that these tubes are sent without cleaning because we need to analyze Corrosion products deposited on these tubes. If possible you may send additional packet of corrosion products that you may have collected from various tubes also. Please also send complete details of layout of tubes, history of failures and also samples of soil where these tubes are laid.
