s235j2 steel hardness chart

The development of modern high-strength steel, s235j2 steel is a process of gradually reducing the carbon content. The reduction of carbon content is beneficial to increase the toughness of steel on the one hand, and can significantly improve the welding performance of steel on the other hand. For large-scale steel structural parts with complex forces that require higher toughness and welding performance, a carbon content design of ≤0.10% is usually adopted.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.

Material type deep processing, that is, the product after deep processing still belongs to the nature of raw materials, this kind of s235j2 steel deep processing has been widely developed, so it is called the traditional deep processing of steel.Broad sense, in the production of steel products to pass through the cold hot working wood timber are belong to the type material deep processing, such as manufacture, paint coating plate, cold bending steel, s235j2 steel welded steel pipe, welding steel cold drawn section steel, steel rods, silver steel rods, wire products (cold drawn steel wire, steel hinge line, cord, piano wire, steel wire, cold heading steel wire) and other all belong to such.
