The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel S420ML equivalent ASTM material specification chart, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.

The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition S420ML equivalent ASTM material specification chart is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for S420ML equivalent ASTM material specification chart various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several S420ML equivalent ASTM material specification chart after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

Chromium element (Cr element) can improve the strength and hardness of S420ML equivalent ASTM material specification chart, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
