What is the smelting process of EN steel grade S275N material

The difference between Q195 steel and 20# steel: EN steel grade S275N material, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.

In the cutting process of wear-resistant plate, EN steel grade S275N material, the steel plate is processed first, because the steel plate is cut after cutting and marking; the commonly used cutting methods for wear-resistant plate are CNC flame cutting and numerical control water cutting, the cost of numerical control flame cutting is not very high, it belongs to primary processing, and its processing range is from 3 mm to 100 mm steel plate. And numerical control water cutting is mainly used under the condition that cutting is required not to deform.

The work concept attaches importance to talents, creates a high-income and high-standard employment mode and work mode, actively advocates all kinds of talents to inspire each other, respect each other, unite and act together, cultivates employees' corporate interests above all else, is tolerant and enterprising, learns correct ways of doing things, improves employees' Professional quality, encourages and urges employees to make continuous progress, Continuously realize self value and grow together with the enterprise.

The consistent tenet of honest management! Know the needs of customers, for the needs of customers, urgent customers think! Our quality is better for the EN steel grade S275N material same products, our price is lower for the same quality, and our service is better for the same price. welcome to purchase steel materials from our company. we have the professional team and good after-sale system to customers. our company EN steel grade S275N material is your best choose.
