mechanical properties of nm550 material properties
The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, mechanical properties of NM550 steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.
SA517GrQ material is a high-strength quenched and tempered alloy steel plate, which belongs to the steel for offshore oil drilling racks. The upper limit of SA517GrQ steel plate thickness is 150mm, and the upper limit of rack steel is 177.8mm. BBN STEEL has opened up a new heat treatment process route for the 177.8mm thick offshore platform rack steel A517GrQ, and strives to improve the production capacity of this product.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. mechanical properties of NM550, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
Just as mechanical properties of NM550, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
Provide special product requirements to meet the personalized needs of customers. The mechanical properties of NM550 company arranges production and shipment strictly according to the contract, and guarantees to supply goods according to the time agreed in the contract. Provide professional consultation: we guarantee to answer any professional and mechanical properties of NM550 technical questions raised by users within 1 hour; provide detailed information.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our mechanical properties of NM550 products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
