201 لوله بی سیم از فولاد ضد زنگ ASTM A554 SS لوله بی سیم با نرخ سخت شدن کار بالا
201 Stainless Steel Seamless Pipe ASTM A554 SS Tube with Mill Test Certificate The 201 Stainless Steel Seamless Pipe is an austenitic chromium-nickel-manganese alloy that provides an economical solution for moderately corrosive environments. Compared to standard carbon steel, it delivers superior oxidation resistance and significantly higher mechanical strength. At ZhongCheng, we manufacture these pipes in strict accordance with ASTM A554 / A312 standards, ensuring precise
لوله های فولاد ضد زنگ با قدرت بالا ASTM A789 مقاوم در برابر خوردگی
ASTM A789 / A789M covers the requirements for seamless and welded duplex stainless steel tubes for general corrosion-resistant service, with particular emphasis on resistance to stress corrosion cracking. This product combines the excellent toughness of austenitic stainless steel with the high strength of ferritic stainless steel, while offering superior resistance to chloride-induced pitting and crevice corrosion. This product covers common grades including UNS S31803,
لوله بدون درز مقاوم در برابر اسید SS316 با کربن کم مقاومت برتر در برابر سولفوریک
Acid-resistant 316 seamless tube is a premium austenitic stainless steel product specifically designed for service in acidic and chemically aggressive environments. The addition of 2-3% molybdenum distinguishes this grade from standard 304, providing significantly enhanced resistance to a wide range of acids, including sulfuric, phosphoric, acetic, and organic acids, as well as chloride-induced pitting and crevice corrosion. The seamless manufacturing process ensures uniform
UNS S31803 لوله بدون درز ASTM A789 4 "جدول 40 لوله فولاد ضد زنگ
UNS S31803 duplex stainless steel pipe is a widely used duplex grade that offers a balanced mix of good strength, excellent corrosion resistance, and cost-effectiveness. It is the original standard duplex stainless steel, commonly specified in ASTM A790 and ASTM A789 for both seamless and welded pipe applications.With a dual-phase microstructure (austenite + ferrite), UNS S31803 provides approximately twice the yield strength of 304 or 316L austenitic stainless steels, while
لوله های فولادی فولادی دو طرفه 2205 بدون درز ASTM A790
2205 duplex stainless steel pipe offers a balanced combination of high strength and excellent corrosion resistance, making it the preferred choice for industries such as oil & gas, chemical processing, marine engineering, and desalination plants. With a duplex microstructure (approximately 50% austenite + 50% ferrite), 2205 provides nearly twice the yield strength of common austenitic stainless steels like 304 or 316L, while maintaining good weldability and fabricability. Key
ASTM A789 UNS S32750 لوله های فولادی ضد زنگ دوگانه برای زیردریایی دریایی
ASTM A789 UNS S32750 super duplex stainless steel tube is a premium-grade product designed for the most demanding industrial applications. With a higher chromium, molybdenum, and nitrogen content than standard duplex grades (e.g., 2205/S31803), UNS S32750 offers superior strength and exceptional corrosion resistance, particularly in aggressive chloride-containing environments. This tube is manufactured in accordance with ASTM A789, covering both seamless and welded ferritic
ASTM A240 UNS S32760 فولاد فولادی فولادی فولادی فولادی
UNS S32760 is a super duplex stainless steel plate that offers an exceptional combination of high strength and outstanding corrosion resistance. This grade is designed for service in aggressive environments where conventional stainless steels such as 316L or even standard duplex grades like 2205 are insufficient. The chemical composition of S32770 is carefully balanced with high levels of chromium, molybdenum, and nitrogen, along with a controlled addition of tungsten and
ورق فولادی ضد زنگ دوبلکس UNS S32750 304 316L برای محیط های تهاجمی
UNS S32750 is a super duplex stainless steel sheet that delivers outstanding corrosion resistance combined with high mechanical strength. This grade is specifically engineered for service in extremely aggressive environments, including high-chloride seawater, acid chloride media, and sour gas applications. As a super duplex grade, UNS S32750 features a balanced microstructure of approximately 50% austenite and 50% ferrite. This dual-phase structure provides approximately
لوله های فولادی ضد زنگ 316L با دیوارهای ضخیم
316L stainless steel welded pipe is manufactured by roll-forming stainless steel coil or plate into a tubular shape, followed by longitudinal welding. As an ultra-low carbon molybdenum-bearing austenitic stainless steel grade, it offers significantly improved resistance to intergranular corrosion after welding compared to 316 stainless steel, while retaining the excellent chloride pitting and crevice corrosion resistance provided by molybdenum.It is produced from high-quality
