A2-70 Bolt

A2 70 Bolt

We are a leading manufacturer of stainless steel bolt and nuts. There are different materials used for producing bolt and nuts. Great Steel & Metals produces all material grades, shapes and sizes of these products. Our A2 70 Hex Head Bolt is made up of the acid proof austenitic stainless steel. It is made up of either 304 or 304L raw material. the specification adapts to minimum tensile strength bolt and nuts. We manufacture the A2-70 Bolt which is made from 304 steel as well but is less commonly used. It is an austenitic stainless that is mostly non magnetic. The material could become magnetic when cold worked. There are A2-70 Stainless Steel Nuts as well, which are used in acid proof systems with minimum tensile strength. Our bolt and nuts with minimum tensile strength are mostly used in acidic environments and are meant for corrosion resistant rather than strength. There are other variations bolt and nuts such as the A2 70 studs, the A2 70 Nut Bolt and the A2 70 Threaded Rod. The A2 70 Allen Bolt is usually added in applications which need much strength rather than corrosion resistance. A different type A2 70 Stainless Steel Bolt which has slight difference in composition opposed to most ISO 3506-1 A2 70 Bolts and it is made up of 302 or 304 stainless steel. Our A2 70 SS Hex Bolt are all made up of superior quality material.
