ASME SA 193 SS B8M Stud Bolts contains both chromium (usually 18 %) and nickel (usually 8 %) metals as the main non - iron constituents. ASTM A193 Grade B8M Stud Bolts ASTM A193 Grade B8M Stud Bolts
ASTM A193 B8M Bolts B8m Class 2 Bolts Gr B8m Studs Specifications Of ASTM A193 B8M Bolts. Dimensions. ASME B18.2.1, B18.3. Melt Origin. South America/East Europe/JapanKorea/. Product Origin. Made in India. Threads Configuration. ASME B1.1 2A/3A Inch Unified Threads and B1.13M 6h Metric Coarse Threads.
Made from 316 stainless steel, these Grade B8M screws are more corrosion resistant than 18-8 stainless steel screws and have excellent resistance to chemicals and salt water. Screws meet ASTM A193 regulations, so they can be used in high-pressure and high-temperature applications. Also known as pressure bolts.

ASTM A193 Grade B8 - Boltport FastenersASTM A193 Grade B8 is a standard material specification for high tensile 304/304L stainless steel bolts, screws, studs and other external threaded fasteners, for use in high temperature or high-pressure service and other special purpose applications.
ASTM A193 Grade B8M Mechanical Properties. Find typical requirement for ASTM A193 Grade B8M Mechanical Properties. Tensile, yield strength and hardness requirement of finished products manufactured to ASTM A193 Grade B8M specification must comply with below requirement. AISI 304/304L with carbide solution treatment can achieve mechanical requirements of A193-B8 Class 1
ASTM A193 Grade B8 Specification - Boltport FastenersASTM A193 Grade B8 Specification ASTM A193 Grade B8 specification covers requirements for 304/304L stainless steel bolting material with high tensile properties, for use in high temperature or high-pressure service and other special purpose applications.
ASTM A193 Grade B8M Bolts Screws Studs Stud Bolts ASTM A193 Grade B8M Studs Specification. AISI 316 is an austentic grade second to 304 in commercial importance It has additional molybdenum which gives improved corossion resistance when exposed to chlorides, it is immune to grain bundaries carbide precipitation. It is suited to use in heavy guage (over 6mm welded component) stainless steel 316
The ASTM A193 grade B8m class 2 Stud Bolts are then quality checked for finish of threads and are verified against there required chemical and mechanical properties. Lastly the material is paired with their relevant nut i.e. A194 Grade B8M Hex and heavy hex nuts for depending on metric or imperial sizes.
ASTM A193 Powered by Portland BoltASTM A962 is a related specification that covers a group of common requirements as they relate to the A193 specification. Section 13 of the A962 specification addresses thread form and class. Threads shall comply with ASME B1.1, Class 2A and can be cut or rolled.
Applications ASTM A193A193 bolt grade selection will be dependent upon the valves base material, the pressure class of the valve, and service conditions. For plain carbon steel valves, Grade B7 bolts are typically used. When high temperatures dictate the use of Cr/Mo valves, Grade B16 bolts are the norm. A193 Grades B8 and B8M are used with stainless steel valves.
The grade B8M or in this case the ASTM A193 B8M Bolts are manufactured from austenitic stainless steel alloy 316. Per the specification, the astm a193 grade b8m threaded rod is designed to withstand not only high temperature, but also high pressure settings.
