S420ML hardness made in China

Comparison of stainless steel 304 and 304L: The main difference between 304L and 304 is the carbon content. The carbon content of 304 is less than or equal to 0.08, and the carbon content of 304L is 0.03 max. Secondly, S420ML hardness, 304 stainless steel is a versatile stainless steel, which is widely used in making equipment and parts that require good comprehensive performance (corrosion resistance and formability), and 304L is a variant of 304 stainless steel with a low carbon content, which is used for Welding occasions.

The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the S420ML hardness enterprise, and make our own contribution to the development of the world economy.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing S420ML hardness steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of S420ML hardness etc. steel material.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
