Stainless Steel 304 Screw

ASTM A193 Grade B8 CSK & SS 304 Sheet Metal Screws manufacturer in India

The A2 grade of stainless steel indicates that the alloy of the SS A2-80 Screw have been cold worked, while the number ‘80’ in these bolts indicate the minimum tensile strength met by the end product . This end product could include manufactured items like screws, nuts or bolts. The 304 Stainless Steel Screw have a high tensile strength of 800 Mpa and are generally manufactured from the Austenitic 304 or 304L grade Stainless Steel.

Grade 304 stainless steels are utilized to manufacture the A2-70 AISI 304 Metric Grub Screw as they are an acid proof stainless steel grade. Although the SS 304 Screw can be treated by solution annealing  with heat between the temperature range of 1010 °C - 1020 °C, they cannot be hardened by treating the material with heat. Therefore the SS 304 Concrete Screws is cold worked. Cold working the SS 304 Thread Rolling Screws  not only improves its hardness, but also the tensile and yield strength of the A2-80 Concrete Screw by becoming resistant to deformation.

Stainless steel grade A2-70 Eye screw and Sems Screw can be treated by coating their surface with Teflon, xylon, phosphate, zinc, cadmium or by treating it to hot dipped galvanization. Coating the 304 Stainless Steel Concrete Screws improves its mechanical and physical properties while imparting a good look to the fastener. Techniques used to finish the Extra Fine UNEF threads ASTM F593 304 Coach screws include pickling and passivation of these products.
