In recent years, in line with the development trend of iron and s355 steel grade steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which s355 steel grade are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The prices of steel plates manufactured by different s355 steel grade, weather resistant steel plate manufacturers are different. Besides, the market situation of weather resistant steel plate and the global production and inventory of the whole steel market are also important factors causing the price fluctuation of steel market. What’s more, the downstream construction, real estate, road construction, etc. Factors also has certain effect on the s355 steel grade, weather resistant steel plate price. The more construction, the more demand, the easier for the steel price to rise.

The wear-resistant plate s355 steel grade shows good wear resistance: the chemical composition of the alloy layer contains 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 of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and s355 steel grade hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

Heat treatment is a very important process to improve the performance of s355 steel grade etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

s355 steel grade, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.
