The ASTM A193 B8m Bolts specification covers both alloy steel as well as stainless steel bolting material. The bolting produced from ASTM A193 Grade B8m Bolts are meant to be used for applications in pressure vessels, valves, flanges, and fittings. Typically, the ASTM A193 B8m Class 1 Bolts is used for high temperature or high pressure service, as well as for other special purpose applications. Ferritic steels which fall under the ASTM A193 Grade B8m Class 2 Bolts category must be properly heat treated as, what best suits the high temperature features of each grade. Immediately after rolling or forging, the bolting ASTM A193 B8m Torque material has to be allowed to be cooled.
ASTM A193 Grade B8m Class 2 Bolts
ASME SA 193 B8m CL1 Studs, Hex Bolt and B8m nuts manufacturer in India.
Difference Between B8m Class 1 And Class 2?
The cooling of the A193 B8M Equivalent bolts must be done to a temperature below its cooling transformation range. The chemical composition requirements for each alloy A193 Gr B8M Material have been presented in detail in the specification.

The steel A193 B8M Bolts must not contain an unspecified element for ordered grade to an extent at which the steel Sa193 B8m bolts conforms to the requirements of another grade for which that particular element is a specified element. The tensile property and hardness property requirements of the ASTM A193 Grade B8m Class 2 Bolts have been discussed in the specification. The tensile strength property requirements of the A193 B8m Cl2 has been highlighted by a full size fasteners, wedge tensile testing. Click on the given link for the A193 B8M Torque Chart
The ASTM A193 B8M specification fasteners such as the A193 B8m Stud Bolts are heavily utilized in industries like petroleum and chemical. The ASTM A193 B8m fasteners often find use in applications that involve the construction industry. Although, the ASTM A193 Gr B8m material is frequently available in national coarse or also referred to as UNC thread pitches, if the ASTM A193 B8m Class 1 Torque are being used in traditional applications, threads are specified in the ASTM A193 B8m Pdf mention 8 threads per inch or tpi for those fasteners which have a diameter above one inch.
Fasteners from ASTM A193 B8m Class 1 are similar to Grade B8. But instead of being manufactured from AISI 304 grade stainless steel, the A193 B8 Class 1 has been produced from AISI 316 stainless steel grade. The Type 316 ASTM A193 B8m Class 2 Torque stainless offers superior resistance to corrosion as compared to grade 304 stainless steel. This is due to the added molybdenum content in ASTM A193 B8m Cl2. The addition of molybdenum in the A193 Grade B8 also improves resistance to pitting in chloride ion solutions. The A193 B8 Cl2 bolts demonstrate an increased tensile strength even at high temperatures.
ASTM A193 B8m Class 2 316 grade stainless steel is known to be effective in acidic environments. The use of A193 B8m grade of stainless steel proves highly effective in protecting the fasteners against corrosion caused by acids such as sulfuric, acetic, hydrochloric, formic, and tartaric, as well as acid sulfates and alkaline chlorides. The additional strain hardening operation performed on the A193 B8 Class 2 fasteners not only increases its tensile strength, but also can demonstrate the A193 B8m Class 2 Properties reduced susceptibility to galling.
A193 B8m Class 1 fasteners have been carbide solution treated, on the other hand A193 B8m Class 2 fasteners have been both carbide solution treated as well as strain hardened. The work hardening that occurs during the manufacturing process of A193 B8m Cl.2 fasteners tends to increases their tensile strength. Typically, Sa193 B8m Class 2 fasteners are differentiated by a line under the grade symbol. This line under the grade will appear either on the heads of bolts or the ends of threaded rods. In this case, A193 Gr B8m Class 2 fasteners have been marked as B8MSH with the grade symbol being underlined.
