What is the difference between ordinary carbon steel and 50CrMo4 alloy steel material round bar
In recent years, in line with the development trend of iron and 50CrMo4 alloy steel material round bar steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 50CrMo4 alloy steel material round bar are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Our steel plates for shipbuilding include: Grade AH32, AH36: A common steel 50CrMo4 alloy steel material round bar for shipbuilding that is typically formatted as heavy plates and fabricated surfaces for large, heavy-duty vessels like commercial ships and bulk carriers.Grade DH32, DH36: Another common shipbuilding steel used to construct and retrofit ship superstructures.Grade EH36: A desirable steel for shipbuilding that is available in prefabricated sections and heavy plates for hull construction and superstructure design.
Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from 50CrMo4 alloy steel material round bar. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.
After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the 50CrMo4 alloy steel material round bar, alloy wear-resistant steel plate is significantly improved.
10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. 50CrMo4 alloy steel material round bar, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.
The high strength 50CrMo4 alloy steel material round bar low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of 50CrMo4 alloy steel material round bar ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
