There are roughly five types of surfaces that can be used for stainless steel. They can be combined to produce more end products.The five species are:1. rolling surface processing2. mechanical surface processing3. chemical surface processing4. mesh surface processing and color surface processingThere are also some special surface treatments, but no matter which one is specified, theFollowing steps should be followed:1. Work with the manufacturer to agree on the required surface processing, it is better to prepare a sample as the future batch production standards.2.

The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the end temperature of rolling. When the final rolling temperature is lower than the recrystallization temperature of the steel, it is called cold rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency, but under hot-rolled conditions, the steel is oxidized, and the surface of the product is gray and dark.

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.In recent years, technological progress has significantly improved the quality of plasma cutting of stainless steel plates. These advancements span a range of thicknesses and have reached 6.25 inches.The early plasma cutting consumes a high current and the cutting speed is also very slow.

From the analysis of stainless steel coil application industry, the automotive industry is currently the fastest developing stainless steel coil application field.In the past decade, consumption of stainless steel coil plates for cars has risen from an average of 10kg to 30kg in Japan and more than 40kg in the US.Bus, subway, high-speed railway vehicles and other public transportation tools are also widely used in stainless steel coil plate.China's home appliance industry is a potential large market for the application of stainless steel coil.In addition, stainless steel coil in the water

Recently, the price of stainless steel 904L has fluctuated more frequently. Supported by many factors such as raw materials and inventory, the price center has basically maintained an upward movement. The demand release situation is good, and the overall social inventory shows a downward trend. The stainless steel market is still running at a high level, and the spot transaction volume has increased. The price of raw materials has risen, but the overall market is not as calm as in 2016-2017.

What is the difference between 2507 stainless steel plate and 2205 and 2206? 2507 stainless steel tube is a ferritic - austenitic (duplex) stainless steel, which combines many of the most beneficial properties of ferritic and austenitic steels. Due to the high content of chromium and molybdenum in the steel, it has excellent resistance to spot corrosion, gap corrosion and uniform corrosion.

When selecting stainless steel in corrosive environment, in addition to having a detailed understanding of the specific service conditions of stainless steel, the main factors to be considered include: corrosion resistance, strength, toughness and physical properties, processing, formability, resources, price and difficulty of obtaining.Corrosion resistance includes rust resistance and resistance to acid, alkali, salt and other corrosive media, as well as oxidation resistance, vulcanization, chlorination and fluorination at high temperature.

Since the end of July this year, the prices of all metal materials have begun to rebound and prices have risen.So, what other factors affect the price ups and downs besides raw materials?First of all, the composition of stainless steel, that is, stainless steel raw materials, stainless steel raw materials are mainly iron, chromium Cr, nickel NI, the price of these raw materials has played a decisive role in the price of stainless steel.

Corrosion resistanceInternational corrosion resistance of materials according to the annual corrosion rate is divided into three categories, the first category for complete corrosion resistance, the corrosion rate is less than 0.1mm / year, high-quality stainless steel belongs to such materials; the second category for still corrosion resistance, the corrosion rate of 0.1-1.0mm / year, belongs to the general stainless steel; the third category for corrosion resistance, the corrosion rate is greater than 1.0mm per year.Cold rolled descriptionCold rolled: Hot rolled coil is used as raw material,
