What is S420NL carbon steel material steel grade

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 S420NL carbon steel material department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and S420NL carbon steel material after-sales service department constitute the service customer network.

The material used for the elbow is carbon structural steel or high-quality carbon structural steel 20#. These two materials can not only ensure that the carbon steel elbow has good hardness, strength and wear resistance, but also ensure the plasticity of the elbow, and ensure that the elbow will not be broken or wounded due to stress during forming. However, cast steel elbows are also used in some special piping systems. This type of piping system requires high mechanical properties of the elbow, and it is difficult to form by forging and other methods in the process.

S420NL carbon steel material, Wear resistant steel plate has good wear resistance:The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce S420NL carbon steel material, hot-rolled seamless steel tube by continuous rolling mill.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. S420NL carbon steel material, 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%.
