Astm A193 B8c Bolts

ASTM A193 B8C Bolts, ASTM A193 Gr. B8C Stud Bolts, ASTM A193 Grade B8C Fasteners, ASME SA193 Gr. B8C Fasteners Manufacturer in India.

ASTM A193 B8C Bolt is a standard specification for grade 347 stainless steel. It has excellent chemical and physical properties. These bolts are made from superior quality raw materials. The grade itself has some outstanding properties, which is why it is used for industrial and commercial uses. The ASTM A193 B8C bolts hold two or more objects steadily together. These bolts are similar to threaded fasteners, and they are further divided into various parts. 

Bolts need nuts to hold and lock the material. These bolts are commonly made of steel material for long-term usage. These bolts are categorized considering their strength, shape, and material. The ASTM A 193 B8C bolts are available in various types. 

ASTM A 193 B8C bolts are among the most ductile bolts today. These bolts are used in high-temperature applications because of their high heat-bearing capacity. 

ASTM A193 B8C bolts are made from chromium, nickel, manganese, phosphorus, carbon, etc. All these elements are known for providing strength and durability to the grade.It also provides excellent resistance from corrosion, crevice corrosion, and stress cracking. These bolts can easily withstand heat and bad weather conditions.
