HARDOX steel SA514 grade B steel material is a famous wear-resistant steel brand. It is designated as Hardox400, hardox450, hardox500, hardox600. It has good wear resistance in general and special applications.

Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, SA514 grade B steel material quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of SA514 grade B steel material etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in SA514 grade B steel material etc. steel is strictly controlled.

SA514 grade B steel material, 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.
