In recent years, in line with the development trend of iron and stal S420M steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which stal S420M are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel. stal S420M, Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm. Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.
Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as stal S420M, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.
How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of stal S420M, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.Ultrasonic testing of 16MnDR steel plates: The stal S420M plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.
