Classification of Stainless Steel Bolts
Stainless steel bolts are classified into various materials, with SUS201, SUS304 (A2-70), SUS316 (A4-70), SUS316L, and B8 commonly used in the fastener industry.
SUS201, also known as stainless iron, serves as a cost-effective choice for environments not requiring extensive rust resistance.
SUS304 (A2-70) is widely preferred in the fastener market due to its commendable corrosion resistance, rust resistance, and moderate pricing, making it a highly selective option.
SUS316 (A4-70) is primarily employed in corrosive environments, such as the chemical industry, where its excellent corrosion resistance surpasses that of SUS304.
B8, denoting A193-B8 bolts and A194-B8 nuts in the American Standard, is composed of SUS304 stainless steel.
These classifications cater to diverse needs, providing versatile options for various applications and environments.
