nm500 gb standard sheet made in China

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 NM500 gb standard sheet department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and NM500 gb standard sheet after-sales service department constitute the service customer network.

Normalizing process of S355J2 steel plate: normalize the S355J2 steel plate in the bottom furnace, normalizing temperature is 880-910℃, holding time is 1.8-2.2min/mm, that is to get the required S355J2 + N steel plate. 355j2 + N steel plate is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields. With the continuous development of economy and the large-scale demand of equipment, the demand of ultra thick NM500 gb standard sheet, S355J2 + N steel plate is increasing gradually.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates NM500 gb standard sheet for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest NM500 gb standard sheet processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain NM500 gb standard sheet by rolling method.

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. NM500 gb standard sheet, EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness. EN10083-3 42CrMo4 steel plate has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
