What is the wear resistance of nm400 surface test

At the same time of doing well in wear resistance of NM400 production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the wear resistance of NM400 technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. wear resistance of NM400. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

Corrosion resistant steel prices are generally higher. What are the applications of wear resistance of NM400, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.

wear resistance of NM400, Wear-resistant steel plates are composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal circumstances, the thickness of the alloy wear-resistant layer of the wear-resistant steel plate is 1/3-1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces. And the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

42CrMo alloy steel wear resistance of NM400: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide wear resistance of NM400 cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about wear resistance of NM400 ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.

Our company will accept the product quality objection registration record, pass it to the wear resistance of NM400 production unit and relevant departments, and timely coordinate the supervision of product wear resistance of NM400 quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
