After more than 20 years of ups and downs in the steel industry, BBN company's customers have covered South America, North America, Europe, Africa, Southeast Asia and the Middle East and other countries and regions. We treat every customer who inquires with us sincerely, whether you cooperate with us or not, we will provide you with the best quality steel solutions. Our company team also support the online customer service.
As a leading S420ML grade equivalent, S420NL hot rolled plates and sheets supplier, we can supply structural steel S420NL plates up to 250mm. It is often delivered in normalized or normalized rolled condition. When customers need doing the third party inspection for S420NL steel plates,our mill would issue the MTC under format EN10204 3.2, the third party can stamped and report the result on our original MTC when inspection is done completely.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, S420ML grade equivalent, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
Try to use S420ML grade equivalent high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the S420ML grade equivalent temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide S420ML grade equivalent reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.
