A4 50 Stainless Steel Bolts and ISO 3506-1 A4-80 Stud Bolt Manufacturer in India
A4-50 Stainless Steel Bolts are austenitic steel bolts which have high corrosion resistance. The A4-80 Stud Bolt is also austenitic but is used in low tensile strength applications with high corrosion resistance especially against acids. The ideal use of A4-70 Nut is in the chemical industry. The A4-70 Stainless Steel Bolt can be used with a balance of strength and corrosion resistance; they have higher strength than the A4 70 Bolt. The A4 80 Hex Bolt belongs to the A4 series and it is a part of A4-70 Bolt And Nut which are corrosion resistant and stronger but still considered minimum tensile strength. Therefore the use of A4-70 Allen Bolt is mainly in chemical industries and in acidic environments where the A4 Stainless Steel Bolts can withstand much corrosion but not high strength. The bolts are also made in the A4 series such as A4-50 Bolt which could be used interchangeably with other grades such as the A4-80 Nut but are usually applied with the same material nuts. We are a leading manufacturer and supplier of A4-50 Stainless Steel Bolts and we also produce A4-50 Screw. Our A4 Marine Grade Stainless Steel Screws could be used under high chloride rich environments and can withstand high corrosion. The A4-70 Threaded Rod produced by Great Steel & Metals is used to lock onto hard surfaces with stronger connection. Please contact us for further details.

A4-70 Stainless Steel Fastener is perceived by 2 different ways, A4 which depict it as being from Stainless Steel 316 family and 70 which classifies its strength. At the point when we say A4-70 it for the most part implies that the bolts/screw is from Stainless Steel 316 grade and has an tensile strength as 70 kg or 700 n/mm2.
