1/4" x 4" x 12" Plate EN 10025-6 high strength steel 1.8931

EN10025-3 S275N steel is a normalized or normalized rolled weldable fine grain structural steel grade. S275N plates shall be under normalized delivery condition and be done low temperature impacting test at -20℃when rolling. If customers request the limited for some chemical compositions, such as P and S,our mill also can satisfy this strict request when processing owning to our highest technical. For the available thickness, EN 10025-6 high strength steel 1.8931, S275N plate is supplied up to 250mm.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. EN 10025-6 high strength steel 1.8931, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

As the thickness and hardness of EN 10025-6 high strength steel 1.8931 increase, the tendency to crack at the cutting edge increases. In order to prevent the EN 10025-6 high strength steel 1.8931 from cutting cracks, preheating should be carried out before EN 10025-6 high strength steel 1.8931 cutting. Special attention should be paid to preheating to make the entire EN 10025-6 high strength steel 1.8931 interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole EN 10025-6 high strength steel 1.8931 cannot be preheated, the partial preheating method can be used instead.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality EN 10025-6 high strength steel 1.8931 products and excellent services. Our company's products EN 10025-6 high strength steel 1.8931 are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
