Murad Fasteners caters to various industries, including oil and gas, power generation, industrial machinery, chemical processing, and construction, providing products that adhere to international standards. With impressive corrosion resistance and excellent load-bearing capabilities, their Stainless Steel 420 Fasteners guarantee secure fastening, durability, and a long service life even in tough environments.
The Stainless Steel 420 Fasteners are made from martensitic stainless steel, which contains about 12–14% chromium along with controlled carbon content. This specific composition allows for heat treatment that enhances hardness and strength. They boast mechanical properties such as good tensile and yield strength, high hardness, wear resistance, and reasonable toughness. While they offer moderate corrosion resistance, they maintain their mechanical integrity under stress and at moderately elevated temperatures.
