nm550 steel chemical composition chemical composition and mechanical properties

It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation. In case of any problem in the use of our steel products NM550 steel chemical composition , whether quality problem or not, the after-sales service department will assist in solving the problem as soon as possible, and regularly consult and track the use of the steel products.

The boiler and pressure vessel steel plates are our main products. Our main conducted standards for boiler and pressure vessel steel plates are (ASME) ASTM (S)A202, (S)A203, (S)A204, (S)A285, (S)A299, (S)A302, (S)A387, (S)A515, (S)A516, (S)A517, NM550 steel chemical composition, (S)A533, (S)A537, (S)A612, (S)A662, (S)A841, EN10028-2, EN10028-3, EN10028-5, EN10028-6, JIS G3115, JIS G3103, GB713, GB3531, DIN 17155, JIS G3116, GB6653, EN10120, etc. Our typical boiler and pressure vessel steel grades are A204 grade B, A516 grade 70, A537 class 1, A537 class 2, 16Mo3, Q245R,Q345R, etc.

The requirements for toughness impact energy of NM550 steel chemical composition, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the NM550 steel chemical composition and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".

The company is mainly engaged in NM550 steel chemical composition steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work NM550 steel chemical composition together for a better tomorrow.
