For S420NL weldable fine grain structural steel plate, it is produced under specification EN 10025-3. The yield strength of S420NL plate shall be above 420Mpa for the thickness below 16 millimeter, 400MPa min. for thickness below 40mm, 390MPa min. for thickness below 63mm. The tensile strength for thickness below 100mm of this steel grade S420NL shall be within 520-680Mpa. For the Mill test certificates of steel S420NL,S690QL steel hardness, our mill would like to issue format according to EN 10204 3.1.

Chemical elements of 35CrMnSi steel: C: 0.32-0.39, Si: 1.10-1.40, Mn: 0.80-1.10, Cr: 1.10-1.40. The mechanical properties of 35CrMnSi steel: tensile strength 1620 MPa; yield strength 1280 MPa; elongation after fracture: 9%; reduction of area: 40; impact energy: 31J. S690QL steel hardness, 35CrMnSi steel is used to manufacture medium speed, heavy load, high strength parts and high strength components, such as aircraft landing gear and high pressure blower blades. 35CrMnSi can partly replace the corresponding CrNi alloy steel in manufacturing small and medium section parts.

On September 14th 2019, a Australia customer purchased 500 tonsDIN17155 15Mo3 boiler steel plates, which will be used for vessel modification of wax backflow protection project and LPU project. Many old customers keep asking about Din17155 steel grade-15Mo3. Usually our company would suggest customers to choose EN10028 steel specification, but if customer insiste on the old steel grade, we could arrange it either. With years of experience in produceing DIN 17155 15Mo3 boiler steel plates, the company supplies high quality steel S690QL steel hardness product with low cost and better service.
