Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and 150mm GL-FH 40 hull structural steel heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported 150mm GL-FH 40 hull structural steel to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
SA299GrB steel plates with a thickness of less than or equal to 50mm are usually delivered in the rolled state, and can also be delivered in the state of normalizing, stress relief, or normalizing plus stress relief. Steel plates with a thickness greater than 50mm should be normalized heat treatment. It can also add flaw detection standard requirements, flaw detection level requirements, alloy element composition control requirements, etc. according to needs.
High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, 150mm GL-FH 40 hull structural steel, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.
Oxygen is a harmful element in 150mm GL-FH 40 hull structural steel steel. With the increase of oxygen content, the strength of 150mm GL-FH 40 hull structural steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of 150mm GL-FH 40 hull structural steel steel.
Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, 150mm GL-FH 40 hull structural steel, and can be used instead of 40CrNi steel.
The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate 150mm GL-FH 40 hull structural steel after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our 150mm GL-FH 40 hull structural steel steel mill.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
