Din 17102 weldable normalized fine grain structural steel plate WstE420 is mainly used in Germany industry. Gnee roll steel grade WstE420 completely according to DIN 17102.When delivery of structural steel plate WstE420,our mill would issued the original mill test certificate under format EN 10204 3.1 type.In MTC,there should be main elements chemical composition,mechanical property and the result of the basic and additional test.Steel grade,dimension,mill’s logo and heat number or batch number shall be hard stamped on each steel plate.
Steel StE255 is used for special requirements according to DIN 17178 : 1986-5 for welded steel tubes and according to DIN 17179 : 1986-5 for seamless steel tubes. These steel tubes are used above all in pressure vessel construction, apparatus construction, pipe construction, as well as in general machine and equipment construction.
High strength low alloy Q355D steel plate are better using than Common carbon structural steel plate Q235B.Q355D steel sheet shall be done Charpy V impacting test at -20 Degree Centigrade when offering.Q355D steel material is equivalent to S355J2 steel material in European specification EN 10025-2.
Steel plate St52-3 is most normal used among all kinds of low alloy steel grades.It is equal to Chinese steel grade Q345B,low alloy high strength steel plate. Low alloy steel plate St52-3 is used to manufacture the plants of factory ,the common constructure and construction machinery and equipments.The additional technical requirements for structural steel plate St52-3 shall be Ultrasonic examination,heat treatment,low temperature impacting,shot blasting and painting for prevent rusty when transport.
St37.3 steel in steel standard DIN 17100 which applies to steel sections (including wide flange beams),steel bars,wire rods,flat products such as steel strip,steel plate,steel wide flats,seamless and welded steel pipes,square and rectangular hollow sections,forgings and semi-finished products in the general structural steels which are delivered in the hot formed or normalized condition after production.Xinsteel onwed ten thousands tons carbon steel plate and coil St37-3 in our port warehouse which is ready for shipment.
Din17100 Rst37-2,Rst37.2 steel is for general structural purposes.Steel plate Rst37-2 is for use in welded,riveted and screwed struatural components,it is not intended for heat treatment apart from stress-relieving heat treatment and normalizing.Now Gnee roll steel plate Rst37-2 range shall be thickness from 2-650mm,width from 1200-4000mm and length from 4000-14000mm.For the special cutting or welding pieces,Xinsteel would like to provide processing services in our plant according to the end users’s drawing.
