If you are experiencing difficulty in selecting the correct s420 steel equivalent steel plates for your business, we have a team of experts who can give you the best advice on steel plates, a significant contributor that can flourish your business.

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, s420 steel equivalent, (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.

Our prime quality high strength structural stel plates retain the acidic attacks in tough climatic environments. These steel plates are heat-treated at very high temperatures of the heat; further, these are cold and hot workable steel. Our plates and sheets have excellent superior weldability. A572 Gr.50 dual certified plates s420 steel equivalent undergo many tests after the production such as corrosion test, pitting corrosion test, flattening test, flaring test, radiographic test and so on.

Although s420 steel equivalent, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

42CrMo alloy steel s420 steel equivalent: low temperature tempering welding performance thermal processing
The heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export s420 steel equivalent to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel s420 steel equivalent plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
