Key smelting points to ensure the successful production of S355J2WP steel grade

45Mn2 steel is added with manganese on the basis of No. 45 steel. After quenching and high temperature tempering, 45Mn2 steel can obtain high strength and good toughness, that is, it has good comprehensive mechanical properties, and is often used in manufacturing larger load shafts, connecting rods, fasteners, etc. The price of 45Mn2 steel is higher than that of No. 45 steel, S355J2WP steel grade. And the performance of 45Mn2 steel after heat treatment is better. 45Mn2 steel can be used as parts under higher stress and wear conditions, such as universal joint shaft, axle, connecting rod cover, friction plate, etc. The performance of 45Mn2 steel after heat treatment is better than No. 45 steel and worse than 40Cr steel.

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's S355J2WP steel grade industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate S355J2WP steel grade market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, S355J2WP steel grade high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of S355J2WP steel grade wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

The allowable temperature of S355J2WP steel grade, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of S355J2WP steel grade work, the actual stress of S355J2WP steel grade under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of S355J2WP steel grade under the temperature.

Both parties shall confirm the S355J2WP steel grade material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the S355J2WP steel grade steel plant.
