What are A4 Stainless Steel Screws

What Are A4 Stainless Steel Screws

A4 Stainless Steel Screws are not ordinary material grade screws; it is a key component in the fastening of offshore solar photovoltaic mounts, SS316 material stainless steel screws have superb corrosion resistance and tensile strength, which can be adapted to the ability of the harsh environment of offshore fastener engineering.

Because A4 stainless steel material is high in nickel and chromium as well as molybdenum chemical elements, it can continue to work in the humid and salty working environment, and be protected from corrosion, rust and abrasion.

A4 Classification of stainless steel screws

According to the difference in tensile strength, there are 700Mpa stainless steel screws and 800Mpa stainless steel screws. Both types of stainless steel screws are made of stainless steel 316, the only difference is the difference in mechanical properties. The increase in tensile strength is achieved by dislocation segregation (cold work hardening) after deformation.

The tensile strength of A4-70 screws is greater than 700 MPA.

The tensile strength of A4-80 screws is greater than 800 MPA.

Our Service in A4 Stainless Steel Screws

All stainless steel wires are sourced from large ISO 9001 certificated raw material factories and each batch of raw material is accompanied by a material certificate.

In order to differentiate between the different grades of stainless steel, we stock them in differenct regions. each wire is PMI tested before production to ensure the correctdifferent material is used.

We have thousands of tonnes of stainless steel fasteners in stock all year round, including of course 316 stainless steel screws, which we can arrange for immediate shipment on request, but of course, they must be standard stainless steel products.

If you need to order customized 316 stainless steel screws, whether you need to change the dimensions of individual parts, drill holes, or cut ends, please let us know what you need, and our engineers and technical department will be at your service.

When you want to ask for free samples for testing, please contact us.
