The surface quality of EN steel grade S275NL material shall meet the requirements

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for EN steel grade S275NL material various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several EN steel grade S275NL material after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.

In the cutting process of wear-resistant plate, EN steel grade S275NL 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.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of EN steel grade S275NL material, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.
