The use of ASTM A193 B6 Bolts and a193 b6 stud is a material specification for stainless steel stud bolts, threaded rods and other exterior threaded fasteners with high tensile strength. The SA 193 B6 Studs are made from AISI 410 stainless steel bar or forging stock that has been heat-treated and machined to a minimum tensile strength of 110 ksi. The a193 b7 Bolts are made up of silicon, phosphorus, manganese, carbon and sulphur, all present in trace levels. The ASTM A193 Grade B6 Bolts are heat treated by quenching and tempering the stainless steel at a minimum temperature of 593 °C. The ASTM A193 B6 Stud Bolts' tensile strength can be machined and heat-treated to a minimum of 110 Ksi or 760 Mpa.


Know the durability ofStainless Steel Stud Bolt

ACCORDING TO THE SPECIFICATION, ASTM A193 B6 Stainless Steel Bolts are used in applications that need high tensile strength. The ferritic grade AISI 410 stainless steel is the raw material used to make A193 B6 Stainless Steel Studs. The alloy in this grade of stainless steel comprises roughly 13% chromium. The ASTM A193 Grade B6 is the primary alloying substance after chromium used in the manufacturing of SS 304 Bolts.

You should be aware that the Sa193 Gr B6 Bolts are suited for a wide range of applications. Fasteners with high tensile strength and the ability to withstand acids, chlorine, and alkali compounds in low concentrations are required in pharmacy, food, heat exchangers & coolers, condensers, marine, chemical, and petrochemical.The 316 Stainless Steel Bolts is unaffected by mild acids or chlorine-containing substances; it performs well in oil and gas industry applications where hydrogen sulphide levels are minimal.

Why the demand forSS Threaded Rod increasing?

The Stainless Steel Hex Bolt Manufacturers produces chromium-molybdenum-vanadium alloy steel used to make ASTM A193 Grade B16 bolts and threaded studs. Although the strength criteria for A193 Grade B16 bolts and studs are comparable to those for Grade B7, the vanadium and higher tempering temperature allow the fasteners to maintain their molecular structure and strength at higher ambient temperatures than Grade B7.


AISI 304 stainless steel is used to make ASTM A193 Grade B8 Class 1 bolt and threaded studs. The SS Threaded Rod manufacturers produce carbide solution treatment required on threaded bars and during the heading process for bolts with forged heads when using this austenitic stainless steel.

Carbide solution treatment, also known as solution annealing,is a corrosion-resistant procedure in which fasteners or stainless bars are heated and subsequently quenched in water. After carbide solution treatment, A193 Grade B8 Class 2 bolts are strain hardened to improve strength and minimize corrosion.

Is it worth using Grade B7 bolts?

The Grade B7 bolts and threaded studs are made of chromium-molybdenum steel with quenched and tempered heat treated to achieve the appropriate mechanical qualities strength. The most common grade of A193 bolts used in construction is grade B7. In the marketplace, B7 threaded studs and short, headed bolts are readily available. The Stainless Steel Stud Bolt manufacturersare focusing on increasing production as the demand is rising.
