A387Gr91 plate is a chromium-molybdenum alloy steel. It has the functions of hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a hydrogen environment at medium temperature (350-480 ℃). It also has good low tempering brittleness. SPA-H steel section, A387Gr91 alloy steel is widely used in the manufacture of chemical fertilizers, petrochemicals, and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, shift furnaces, and hydrogenation reactors.
The A283 C mild steel plate comes from the carbon steel which has a low carbon alloy. The mild steel plate/carbon steel plate is a combination of a low amount of chromium, and molybdenum with low carbon as well. Because of the low carbon alloy, it is more weldable, ductile rather than the carbon steel. The mild steel plate SPA-H steel section is created magnetic and has a high amount of ferrite and iron. Mild steel has various characteristics like affordability, easy to weld, machinability.
SPA-H steel section, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.
The carbon content of SPA-H steel section, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
The high strength SPA-H steel section 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 SPA-H steel section ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
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.
