Chanchai Stainless supplies Stainless Steel 420 Bolts in Bangkok, Thailand. These bolts are designed for strength, hardness, and moderate resistance to corrosion. As a martensitic stainless steel, grade 420 can be hardened through heat treatment, providing exceptional wear resistance. They are suited for applications that prioritize strength and durability over corrosion protection. Stainless Steel 420 Bolts deliver good mechanical performance, toughness, and stability in service conditions. Manufactured to international standards, Chanchai Stainless ensures that 420 bolts offer high-quality fastening solutions for automotive, mechanical, and industrial applications where strength and wear resistance are essential.
Stainless Steel 420 bolts contain chromium (12–14%) and carbon (0.15–0.40%), enabling heat treatment for hardness up to 50 HRC. Their mechanical properties include a tensile strength of 655–850 MPa, yield strength of 275 MPa, and elongation of 15–20%. These bolts offer excellent wear resistance along with moderate corrosion resistance. 420 provides good machinability, durability, and strength, making it a cost-effective fastening choice for mechanical and industrial settings.
