In terms of service, our service is a "one-stop" way of working. We have our own EN10083-3 alloy steel 34crmo4 norme processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as EN10083-3 alloy steel 34crmo4 norme cutting, welding, drilling, galvanizing, etc., at the lowest cost.

A514Gr.Q material is a quenched and tempered high-strength weldable steel plate under the ASTM standard. It is mainly used in places where high tensile strength and high yield are required, engineering vehicle lifting gears, and racks for offshore platforms. Depending on the thickness, its hardness is between 235-290, the yield is greater than 630MPa, and the tensile strength is greater than 700MPa.

Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. EN10083-3 alloy steel 34crmo4 norme, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of EN10083-3 alloy steel 34crmo4 norme, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.

When the stainless steel plate is alloyed with chromium, the type of surface oxide is changed to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the steel surface, so that EN10083-3 alloy steel 34crmo4 norme, stainless steel has a unique surface.
