How long will a242 type 1 steel plate last not rust outside?

Since it was established in 2000. Based on the domestic rich a242 type 1 steel plate product resources and the great steel demand of the international market, our a242 type 1 steel plate service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

A709Gr.36 steel plate is used in construction steel structures, construction machinery and other steel structures, and has been exported to South Korea, Singapore, Malaysia, Dubai, Nigeria and other countries. The a242 type 1 steel plate) cumulative export volume has reached more than 10,000 tons. Construction steel structure, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for construction and engineering machinery parts that require good weldability and toughness.

a242 type 1 steel plate, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

The work performance of a242 type 1 steel plate etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.

a242 type 1 steel plate, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

It is a modern high-tech professional enterprise integrating scientific research, a242 type 1 steel plate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as a242 type 1 steel plate process technology development, technology transfer and related technical consulting and technical services.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
