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.

Class Symbols (Applicable till the end of 1990): These tubes are classified into 3 grades and their class symbols are given as: We need to know how we can get Hydrant, Pipes & Sprinkler? The Manufacturer, their address, telephone. Thanks.

Please tell me the material composition of 10B21 boron steel, with the tolerance and permissible limits in %age.

ASTM/ASME A/SA-178 = Grades A and C. Electric Resistance Welded Carbon Steel Boiler Tubes = DIN 17177, Steel 37.8 I - III, Steel 42.8 I - III ASTM/ASME A/SA-179 = Seamless Cold-Drawn low-Carbon Steel Heat Exchanger and Condenser Tubes = DIN 17175, Steel St 35.8, St 45.

DIN (or Deutsche Industrial Normale) is a series of uniformity standards developed in Germany, which apply to commonly manufactured items.

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.

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.

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.

Normally equivalent vacuum tubes such as a 6J5 or 6J5GT or 6J5G are electronically the same. They may have a different construction, i.e. metal versus glass, or a different glass shape. They will perform the same. Substitute vacuum tubes are not exactly the same electronically but will perform the same in most circuits. We will not ship a substitute tube without first checking to see the application it is to be used in.

If you can rub the flux onto the back while heating the sides, the rod will flow all the way around your parent metal to seal the tube [back to top]

Induction annealing of tube is carried out at throughput speeds of up to 100 feet per minute depending on tube size and the size (kw) of the induction heating power supply. A typical induction heating coil is approximately three to four feet in length so the heating time is very short (a few seconds) compared to furnace heating times.
