The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of A514 grade E quenched and tempered steel pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and A514 grade E quenched and tempered steel special properties such as good formability, weldability and adaptability to welding process.
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the A514 grade E quenched and tempered steel project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of A514 grade E quenched and tempered steel customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel A514 grade E quenched and tempered steel usually adopts surface quenching after quenching and tempering as the heat treatment plan.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. A514 grade E quenched and tempered steel, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
FANALCA is the biggest motorcycle factory in Columbia. Meanwhile, it is the only distributor in Colombia for Japanese Honda. We began to cooperate with each other since 2017. We supply SAPH370, SAPH440 and so on automobile steel coils to them. As our products quality is proved to be satisfied during their production, they have been one of our stable customers, and give repeat orders about automobile steel every year.
