What is the difference between S420ML material specification & SS400 ?

The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, S420ML material specification professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better S420ML material specification tomorrow!

Alloy steel plate BBN steel supply: 15CRMO, 20CRMO, 35CRMO, 42CRMO, S420ML material specification, 12CR1MOV, CR12, CR12MOV, 27SIMN, 35SIMN, 42SIMN, 40B, 45B, 50B, 20MN2, 35MN2, 45MN2, 20CR, 40CR, 15MNV, 20CRNIMO, 40CRNIMO, 20CRMNMO, 40VCRMNMO, 50MN2, 9CR18, 9CR18MOV, 16MNCR5, 20CRMNTI, 12CRMOV, 35CROV.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and S420ML material specification steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, S420ML material specification.

GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. S420ML material specification, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic S420ML material specification stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate. Contact us today to request a quotation or email us with your complete specification, we are happy to help you!

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
