What is the difference between S275 and S275JR steel plate?

What is S275JR Plate 

The S275JR PLATE is a steel plate made from mild steel or carbon steel. These plates are having huge usage for the structural building, manufacturing in the plant, machinery building, and in mining. These plates are made of S275JR alloy which is very versatile in nature. This steel is composed of phosphorus, sulfur, silicon, and copper as major elements. It is having carbon and manganese in larger percentage as compared to other steel alloys. The plate made of this steel is having higher yield strength, higher tensile strength and have larger elongation property. The S in the S275JR determines as the correspondence to structural steel. This alloy is having good machining properties and thus it provides finish work at the edges and at the surface. The alloy is also very suitable for the welding purpose and they can also be welded at lower heat and at the lower temperature. These alloys are very slow at hardening process and thus can be shaped and formed even at low temperature although they usually face cold working and cold forming.

What are the chemical composition of S275JR plate?

The S275JR plate chemical composition include a carbon content of 0.25%, a silicon content of 0.4%, a manganese content of 1.5%, a phosphorus content of 0.03%, a sulfur content of 0.03%, and a nickel content of 0.012%.

What is the difference between S275 and S275JR plate?

S275 and S275JR plate are both made to the EN 10025-2 standard. The only difference between the two is that S275JR plate has been impact tested at 27 Joules at room temperature, while S275 plate has not. This means that S275JR plate is more suitable for structural applications that require higher impact S275JR plate yield strength.
