SS 304 Hex Head Bolt and M8 Heavy Hex Bolt manufacturer in India

Stainless steel alloys make good fasteners because they are strong, and have good corrosion resistance properties. The most popular grade chosen by most manufacturers is grade 304, which is also known as grade A2-70. A Stainless Steel Hex Bolts manufacturer in India recommends using this alloy because it is economical while being an effective solution in applications that require good strength, with moderate resistance to corrosion. In comparison to grade 316, which contains molybdenum, grade 304 contains 18% chromium with 8% nickel.

Stainless Steel Hex Bolts

Its chemical composition is also why the A2 70 Hex Head Bolt may be referred to as grade 18/8. Since the chromium content of this alloy is higher than 12%, in oxidizing environments, the rate of oxidation is lower because the outer layer of the alloy forms a self-protecting passivating layer. This passivating oxide layer generated on the surface of the SS 304 Hex Head Bolt prevents the alloy from getting corroded in the presence of oxygen in the air. Although this layer is only beneficial to environments that contain oxidizing media, it is possible to galvanize the fasteners to improve their performance in other environments, with a thick coat of zinc. The main difference between electroplated fasteners and Galvanized Hex Bolts is in the width of the protective coating layer. While plating may be used for aesthetic appearances, they offer very little protection and are suited to those environments which require moderate to very little resistance to corrosion. On the other hand, a thick layer of zinc coat on the galvanized alloy 304 SS Flanged Hex Bolts is ideal for applications that require higher corrosion resistance properties.
