Does JIS SM490YA plates have good low temperature toughness

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the JIS SM490YA plates industry, keep pace with the times, and move towards a new course!

BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, JIS SM490YA plates , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while JIS SM490YA plates steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of JIS SM490YA plates steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe JIS SM490YA plates for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.

35SiMn steel chemical elements: C: 0.32-0.40, Si: 1.10-1.40, Mn: 1.10-1.40. The mechanical properties of 35SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 45; impact energy: 47J. 35SiMn steel belongs to alloy quenched and tempered steel with good properties and can be used instead of 40Cr steel. After quenching and tempering, JIS SM490YA plates, 35SiMn steel has high static strength, fatigue strength, wear resistance, good toughness, good hardenability and medium plasticity during cold deformation.

Group consciousness is an important psychological factor for the formation of enterprise internal cohesion. The formation of JIS SM490YA plates enterprise group consciousness makes every employee of the enterprise regard their work and behavior as an integral part of the realization of enterprise goals, make them feel proud of themselves as a member of the enterprise, have a sense of honor for the achievements of the enterprise, and thus regard the JIS SM490YA plates enterprise as the community and belonging of their own interests.
