What are the effects of phosphorus in spa-h steel yield

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 spa-h steel yield 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 spa-h steel yield to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

SKD5 use: commonly used die-casting die steel. SKD5 steel has low carbon content, high toughness and good thermal conductivity. At the same time, it contains more carbide forming elements chromium, tungsten, and vanadium. The phase transition temperature is increased, so that the steel has high high temperature strength, hardness and good thermal conductivity. Thermal fatigue resistance; hardening. Suitable for manufacturing high temperature, high stress, but not impact load, die-casting copper, aluminum, hot top forging die, convex and concave dies, inserts, etc. of flat forging machines.

EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.

Oxygen (O) is a harmful element in steel such as spa-h steel yield. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

spa-h steel yield, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
