The Fasteners Mart in Mumbai, India, is one of the top suppliers of excellent quality fasteners to an extensive array of industries. The company deals in stainless steel materials and provides long-lasting, dependable fasteners like the Stainless Steel 420 Fasteners. They are produced using Grade 420 stainless steel, which is a martensitic stainless steel having superior hardness, corrosion resistance, and tensile strength properties. Coming in different forms, such as bolts, nuts, and washers, Stainless Steel 420 Fasteners are best suited for applications with high stress demands strength and resistance.
Stainless Steel 420 Fasteners contain mainly 12-14% chromium, which gives corrosion resistance, and up to 0.15% carbon content that is responsible for hardness in the material. The mechanical properties are tensile strength of 500-700 MPa and a yield strength of around 275-450 MPa. Stainless Steel 420 also provides desirable hardness ranges of 50-55 HRC when heat treated. These fasteners have a good resistance to wear, oxidation, and corrosion and are ideal for high-stress and high-temperature applications.
