To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Stainless Steel 420 Fasteners are crafted from a martensitic stainless steel alloy that contains about 12–14% chromium along with a higher carbon content. This unique blend allows for heat treatment, resulting in impressive hardness, strength, and outstanding wear resistance. While Grade 420 fasteners offer moderate corrosion resistance compared to austenitic grades, they also provide good tensile strength and impact resistance when properly hardened and tempered. They maintain their shape under mechanical stress, making them ideal for applications that require both corrosion resistance and mechanical strength.
Stainless Steel 420 Fasteners are commonly utilized in situations that demand high strength, hardness, and wear resistance. You’ll find them in various industries, including automotive, industrial machinery, pumps, valves, and mechanical assemblies. These fasteners are particularly suited for components that face friction, abrasion, and moderate corrosive environments.
