P275NH normalizing can weld refined grain steel. Fine grain steel GL-D40 ore carrier steel plateis understood to be steel with ferrite grain size of 6 or finer after testing according to EURONORM103 standard. Executive standard: EN10028-3, number: 1.0487. P275NH is non-alloy quality steel for pressure equipment. P275NH steel plate has good plasticity, toughness, cold bending performance and welding performance.
The company now has GL-D40 ore carrier steel plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than GL-D40 ore carrier steel plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.
In order to improve the GL-D40 ore carrier steel plate corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main GL-D40 ore carrier steel plate coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking GL-D40 ore carrier steel plate sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of GL-D40 ore carrier steel plate etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in GL-D40 ore carrier steel plate etc. steel is strictly controlled.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
