Military bulletproof steel plate EN steel grade S235J0 material

42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel EN steel grade S235J0 material usually adopts surface quenching after quenching and tempering as the heat treatment plan.

The company's EN steel grade S235J0 material steel products are sold all over the world with high quality and low price. We can process and cut all kinds of special-shaped parts according to your requirements, or we can set and roll futures of all kinds of material specifications according to your requirements, with fast delivery time.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. EN steel grade S235J0 material Heat treatment process refers to the ability to change the microstructure and properties of EN steel grade S235J0 material after heat treatment, including hardenability, hardenability, temper brittleness, etc.

Its weatherability is the protection of the oxide layer of weatherproof steel. The mechanism of corrosion resistance of weathering steel is mainly based on the analysis of long-term exposed rust layer. Generally speaking, it is believed that weathering steel can form a dense layer of weathering rust through long-term exposure, which has a good protective effect on weathering steel, EN steel grade S235J0 material.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
