American Standard ASME SA-193/SA-193M B16 High Temperature Bolt

B16 Purpose: Alloy steel and stainless steel bolt materials for high-temperature pressure vessels, valves, flanges, and pipe fittings.

The chemical composition of SA 193B7M grade bolt material is the same as that of B7 grade, and it is quenched and tempered to achieve a lower

Hardness. Their tensile strength is also lower than that of B7 grade bolts. Typically used in stress corrosion cracking environments/floating head heat exchangers.

SA - 1942HM nuts are similar to 2H nuts and are recommended for stress corrosion cracking environments.

SA-193B16 grade bolts are mainly used for high-temperature applications from 400 ° C to 595 ° C. They are made of chromium molybdenum vanadium alloy steel

The B16 grade bolts have mechanical strength similar to the B7 grade, but the fasteners can still maintain strength at high temperatures

And there is less relaxation at high temperatures. There are two main levels of nuts that can be matched with B16 grade bolts: level 4 and level 7, which are

Chromium molybdenum steel nuts with overheating treatment are suitable for working conditions below zero degrees Celsius, with a minimum temperature of -48 ° C. It should be mentioned that usually

B16 grade bolts must be used together with grade 7 (or 4) nuts because they have similar characteristics.
