s237jr a36 grade S450J0 carbon steel plate sheet hr ms ship building

SA516Gr45 (R-HIC) This type of steel plate is mainly used in the manufacture of equipment used in wet hydrogen sulfide environment, such as: liquefied petroleum gas desulfurization system, stable absorption system for catalytic cracking, condensation system of atmospheric and vacuum distillation tower, etc. The material S450J0 carbon steel plate sheet has the characteristics of high purity, low P, low S, good uniformity of structure and mechanical properties, resistance to hydrogen cracking and sulfide stress corrosion.

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business S450J0 carbon steel plate sheet department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and S450J0 carbon steel plate sheet after-sales service department constitute the service customer network.

S450J0 carbon steel plate sheet annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S450J0 carbon steel plate sheet annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S450J0 carbon steel plate sheet annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

The allowable temperature of S450J0 carbon steel plate sheet, 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 S450J0 carbon steel plate sheet work, the actual stress of S450J0 carbon steel plate sheet under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of S450J0 carbon steel plate sheet under the temperature.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
