What is S420ML steel yield strength price in China

The use of low carbon steel is limited due to its low strength. The strength of the carbon steel can be greatly improved by properly increasing the manganese content in the S420ML steel yield strength carbon steel and adding some alloy elements such as vanadium, titanium and niobium. If the carbon content in the carbon steel is reduced and a small amount of aluminum, boron and carbide forming elements are added, the ultra-low carbon bainite can be obtained, S420ML steel yield strength which has high strength and good plasticity and toughness.

Ordinary medium and thick steel plate S420ML steel yield strength is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.

Titanium microalloying is an element of S420ML steel yield strength strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in S420ML steel yield strength tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than S420ML steel yield strength 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.
