Grade A4-70 Fasteners, Screw, Threaded Rod, and Nuts manufacturer in India
A470 Bolt is made from either the 316 or 316L material grade stainless steel. The A4-70 Stainless Steel Material Specification mandates that the products meet the 700 Newton per millimeter square or 700MPa. The A4-70 Stainless Steel Screw has to withstand this minimum tensile strength. The A4 70 Stainless Steel Strength therefore is higher than the required minimum. The A4-70 Threaded Rod is used to produce the threaded bolts and screws. Jignesh Steel is a manufacturer of fasteners of A4 70 grade and our A4-70 Nut Material is cold worked to produce the different A4-70 Fastener types. The A4-70 Bolt And Nut products are acid proof in most conditions. The applications of the Stainless Steel Bolt Grade A4-70 are therefore mostly in the chemical and acid processing industries. We produce different types of special fasteners such as the Socket Head Cap Screw A4-70 is used applications where the space is limited or narrow. The Stud Bolt A4-70 is used in general applications and is one of the most used forms of the fasteners of this grade. We also manufacture special types of bolts for applications that require high strength such as the Hex Bolt A4-70 and others. Please contact us for a full product catalog and price list.

The a4 70 bolt is manufactured by cold forming 316 grade stainless steel. This austenitic grade stainless steel has a minimum tensile strength requirement of around 700 Mpa, which is indicated by the number 70, as mentioned in the product name - grade a4-70 stainless steel bolts . The minimum tensile strength for this material is required to be in the form of an end product or a manufactured product for example - a4-70 grade stainless steel bolts , nuts or screw.
As compared to the fasteners made from 304 grade stainless steel, the alloy of a4-70 grade 316 bolts have enhanced mechanical properties like – good weldability, ease in fabrication, finishing and cleaning as well as good durability. Additionally, in comparison to nickel chromium grade stainless steels, the a4 70 bolt material is has good heat resisting as well as improved corrosion resistance on exposure to corrosive mediums. The molybdenum content in the a4-70 stainless steel bolt is responsible for its increased corrosion resistance.
Stainless steel fasteners like the a4 70 grade bolts is used in the manufacture of certain pharmaceuticals in order to avoid occurrence of excessive metallic contamination. In terms of resistance to chemicals, the grade 316 a4-70 bolts have better resistance to halogen containing compounds like - iodides, chlorides, bromides, sulfuric acid and fatty acids at elevated temperature. Therefore, due to its good mechanical properties, the grade a4-70 bolts proves to be a valuable addition to various applications. Although, the cost of the a4-70 hex bolt is high, its features improve its work life as well as durability.
