In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product s355 hot rolled automotive steel grade structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel s355 hot rolled automotive steel grade supplier in the world.

Abrasion resistant steel s355 hot rolled automotive steel grade which is also known as (AR steel) wear resistant steel, is developed to have longer service life than mild steel. Abrasion resistant steel is widely used in underground mines, cement industry, road construction, mining and open-pit mining and metallurgical industries and manufacturing other wear-resistant parts.

s355 hot rolled automotive steel grade, Wear resistant steel plate has good wear resistance:
The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.

s355 hot rolled automotive steel grade, Wear-resistant steel plates are mainly made of some alloying elements, such as manganese, silicon, chromium, vanadium, aluminum, titanium, boron, rare earths elements and so on. Generally, manganese and silicon are added first, because this can further strengthen the deoxidation effect, and because their prices are relatively low, adding them early can ensure the yield of the elements added later.

s355 hot rolled automotive steel grade, S235JR VS S275JR VS s355jr plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
