stainless steel seamless pipe
Stainless steel seamless pipe is a kind of economical cross section pipe without seam. Furthermore, seamless stainless steel pipe tubes are broadly utilized in decorative and industrial line; for instance, lots of people use them to make stair handrail, protective windows and railings etc. Therefore, stainless steel seamless pipe is an important product in iron and steel industry.
Name: stainless steel seamless pipe
Steel grade: Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series)
Standard: ASTM A269, ASTM A312, ASTM A789, JIS G3456-88, JIS G3448-88, JIS G3459-88, JIS G3463-88

Main Grade of Seamless Stainless Steel Pipe and Applications:
Grades | Applications |
---|---|
301 | It is used for forming products with good ductility and good weldability. Abrasion resistance and fatigue strength is better than that of304 stainless steel. It can harden rapidly by mechanical processing. |
302 | The corrosion resistance of 302 is the same with 304. Due to high carbon content, intensity is better. |
303 | It is easier to cut processing than 304 by adding a little sulfur and phosphorus. |
304 | It is18/8 stainless steel. GB brand is 0Cr18Ni9. |
316 | After 304, it is the second to get widest applications. It is mainly used to food industry, pharmaceutical industry and surgical equipment. Adding molybdenum elements make 316 stainless steel gets a special structure of corrosion resistant. Because it has much better ability to resist chloride corrosion, it is often used as marine steel. SS316 is usually used for nuclear fuel recycling equipment. |
400 | 400 series Ferrite and martensite stainless steel |
408 | Weak corrosion resistance and good heat resistance. Cr: 11%;Ni:8% |
409 | The cheapest model (), it is usually used as auto vent pipe and is a ferritic stainless steel (chrome steel). |
410 | Martensite stainless steel with good abrasion resistance and weak corrosion resistance. |
416 | Adding sulfur can improve the processing properties of material. |
420 | Rj martensitic steel which is similar to brinell high chromium steel. It is used as surgical tools. |
430 | Ferritic stainless steel with good formability and poor temperature resistance and corrosion resistance. It is mainly used to decorate. |
440 | High strength cutting steel with high carbon. After appropriate heat treatment, it can obtain higher yield strength, the hardness can reach 58 HRC. It belongs to the most hardest stainless steel. The most common example is razor blade. Common models:440A, 440B, 440C. |
500 | 500 series-heat resistant chromium alloy steel |
600 | 600 series-martensitic precipitation hardening stainless steel pipe |
