SUS304 Stainless Steel Pipes
SUS304 Stainless Steel Pipes
Stainless steel pipes can be divided into Cr series (400 series) and Cr ni series
(300 series), Cr Mn Ni (200 series), and precipitation hardening system (600 series). 200 Series - Chromium Nickel Manganese
Austenitic stainless steel, 300 series - chromium nickel austenitic stainless steel.
301- Extension is beneficial for forming products. It can also be hardened through mechanical work. Good weldability. Wearing
The fatigue strength is better than 304 stainless steel.
302 has the same corrosion resistance as 304, as it has a higher carbon content and better strength.
303- Adding a small amount of sulfur and phosphorus is easier to cut than 304.
304- is 18/8 stainless steel. The national standard level is 0Cr18Ni9. 309- has better temperature resistance than 304.
After 316-304, the second most widely used steel grade is mainly used in the food industry, pharmaceutical industry, and
Molybdenum is added to surgical equipment to obtain a special corrosion-resistant structure.
321- Other properties are similar to 304, except that adding titanium reduces the risk of material weld corrosion.
400 series - ferritic and martensitic stainless steel.
408- Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
The cheapest model, usually used for automotive exhaust pipes, is ferritic stainless steel (chromium steel).
410 martensite (high-strength chromium steel) has good wear resistance but poor corrosion resistance.
The addition of sulfur improves the processing performance of the material.
420- Cutting grade martensitic steel, similar to the earliest stainless steel Brinell high chromium steel. Also used for
The surgical knife can be made very shiny.
430- Ferritic stainless steel, used for decoration, such as in automotive parts. Good formability, but temperature difference
Corrosion resistance and corrosion resistance.
440- High strength cutting tool steel with slightly higher carbon content. After appropriate heat treatment, a higher yield can be achieved
The strength and hardness can reach 58HRC, which is the highest among stainless steels. The most common application examples are
Blade. There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process).
500 series heat-resistant chromium alloy steel.
600 series - Martensitic precipitation hardening stainless steel pipes.
