JIS G 3125 SPA H 2mm steel sheet is required to have high toughness

S50C steel plate is a high-quality high-quality medium carbon steel. S stands for steel, which means iron, and 50 stands for carbon content of 0.50%. C represents carbon steel, which means that S50C is a carbon steel with a carbon content of 0.50%.
Mechanical properties of S50C steel plate:
Tensile strength σb (MPa): ≥630 (64); Yield strength σs (MPa): ≥375 (38); Elongation δ5 (%): ≥14; Reduction of area ψ (%): ≥40; Impact Work Akv (J): ≥31(4); Impact toughness value αkv (J/cm2): ≥39(4)
Hardness: unheated, ≤241HB; annealed steel, ≤207HB

In terms of service, our service is a "one-stop" way of working. We have our own JIS G 3125 SPA H 2mm steel sheet processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as JIS G 3125 SPA H 2mm steel sheet cutting, welding, drilling, galvanizing, etc., at the lowest cost.

As the thickness and hardness of JIS G 3125 SPA H 2mm steel sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the JIS G 3125 SPA H 2mm steel sheet from cutting cracks, preheating should be carried out before JIS G 3125 SPA H 2mm steel sheet cutting. Special attention should be paid to preheating to make the entire JIS G 3125 SPA H 2mm steel sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole JIS G 3125 SPA H 2mm steel sheet cannot be preheated, the partial preheating method can be used instead.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, JIS G 3125 SPA H 2mm steel sheet. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
