What are the differences between black and painted SM490A carbon steel material

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the steel industry.

Characteristics of 50CrMo4 steel: 50CrMo4 steel has high strength and toughness, good hardenability and no obvious tempering brittleness. 50CrMo4 steel is suitable for manufacturing large and medium-sized plastic mould with certain strength and toughness. 50CrMo4 steel can be used to manufacture the big gear for locomotive traction, booster drive gear, pressure vessel gear, rear axle, connecting rod and spring clamp with great load, as well as the drill pipe joint and fishing tool for oil deep well below 2000m, and 50CrMo4 steel can also be used for the die of bending machine, etc.

SM490A carbon steel material,NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade. Crusher liner and blade.

After adding a small amount of niobium, vanadium and titanium to the steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

SM490A carbon steel material,Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

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.SM490A carbon steel material
