These bolts are often used in pipe flanges, and to protect the flange, the bolt is designed and manufactured to break before the expensive pipe flange is damaged through over tightening. Editorial Note: ASTM A307 now requires a manufacturer and a grade marks on the top of heads. Grade identification consists of "307A" or "307B" on each bolt produced to its standard requirements.

Tensile strength is the stress (measured in Newtons/m2 or psi) at which a sample of solid material will break from tension. See similar questions...

J-B Weld has a tensile strength of 3,960 psi. J-B Kwik has a tensile strength of 2,424 psi. For more physical properties information, please see the "PRODUCTS" section of this website. See similar questions...

Joint strength depends on several factors: clearance between parts, base metal composition, service temperature and joint quality (low voids, good penetration). Joint design will also affect strength. The bulk tensile strength of silver braze alloys is 40,000-70,000 psi. When brazing copper-based alloys, failure will occur in the copper or brass. For copper this is usually the annealed strength of the copper alloy. See similar questions...

The standard requires that these configurations be stress relief annealed to remove cold work effects, particularly at the junction of head to shank. This is a very important requirement for such products as carriage bolts, for example. See similar questions...

UltraFiber 500™ in concrete has higher fiber tensile strength than typical polypropylene. The fiber tensile strength of UltraFiber 500 is 90-130 KSI, and this compares to typical polypropylene with fiber tensile strength of 30-70 KSI. See similar questions...

ANSWER: A minimum of 5 micrograms per square centimeter of bag surface. Keep in mind that enough retronectin must be added to coat both top and bottom of the interior of the bag. Accordingly add enough retronectin for both surfaces. It is believed that best transduction results are obtained if the retronectin is allowed to attach for two hours at room temperature or 30 minutes at 37 degrees. ANSWER: We made silicone rubber bags about 25 years ago but they were not satisfactory for cell culture. See similar questions...

Steel fibers have greater tensile strength than PVA fibers, but this strength is rarely used. Steel fibers, like rebar, are passive reinforcement, meaning they have no reinforcing effect until the concrete cracks. The problem then is that steel fibers tend to pull out rather than hold the concrete together. Many techniques have been used to increase the mechanical bond of steel fibers--hooks and waffles are among the most popular--but even so the steel fibers pull out easily. See similar questions...

A : Tensile strength can be explained as the amount of resistance/elongation required to withstand a force before being permanently broken, bent or deformed. Hardness means resistance to abrasion/wear. For example, diamonds are amongst the hardest existing materials, but hardness does not necessarily mean "shock-proof". A diamond can break or chip if dropped on a hard surface, as their molecular structure presents natural "weaknesses", called cleavage plans. See similar questions...

The regulations in which the system will have to meet will vary in different parts of the world and the country of use. The two main regional standards are: See similar questions...

Grade B eggshells may have slight blemishes, such as scratches, stains, natural blemishes, etc. They are not cracked or broken in any way. Grade B eggshells are mostly used by artists for painting or carving where these blemishes are covered up. You might want to order a Grade A eggshell if you are planning on displaying it in it's natural state. See similar questions...

The difference is the number of column defect allowed in the CCD sensor. For a grade A CCD, there is no column defect in the central 750 x 750 CCD area. For a grade B CCD, the maximum number of column defects should not exceed 10 in the whole image. See similar questions...

Liquid caustic soda is commonly available in either 25% of 50% by weight. Dilutions to lower strength are available upon request. Both membrane and diaphragm grade is available. All products meet the appropriate AWWA and NSF specifications for caustic soda. See similar questions...

There are some variations across the zones, but in the main the following grades of drivers are usual in the railway hierarchy. A special driver is one qualified to handle mail, superfast, and express trains. An A driver is qualified to handle ordinary long-distance passenger trains. In some zones, there is no separate category of 'A-special', and all 'A' drivers are eligible to drive express trains, but only elite or senior A-grade drivers are assigned prestigious expresses like the Rajdhanis.

We would need 10 specimens (5 non conditioned & 5 conditioned samples) per set of 20 x 150mm x t (where t is your product thickness). Please ensure that pieces are parallel cut. If you send a full sheet, we can prepare required specimen but we will have to charge extra for this job. We will present the values before & after water conditioning and % loss after conditioning, in a detailed fashion as a complete test report. Please note that you must submit samples after conditioning at your end. See similar questions...

We do have salt spray test facility, and maximum length we can test is 500mm. Our charges are Rs. 1,500/- for 1st day and Rs. 1,000/- for each additional day. 10.2% Service Tax shall also be applicable. See similar questions...

If your sample size is 3mm Thick x 20mm wide and if you can send us approximate 150mm long strip then we can carryout all tests needed by you. If your sample length can not exceed 80mm then we may not be able to do Tensile Test but we can do Hardness & Chemical Tests. Cost of such test will be communicated to you only after completion of tests as we do not know how many elements may be needed to analyze at this stage. See similar questions...
