UNS S30403 لوله بدون درز از فولاد ضد زنگ TP304L قابل جوش بدون درمان حرارتی پس از جوش
UNS S30403 seamless pipe is a low carbon version of the standard 304 austenitic stainless steel, designed for applications requiring enhanced resistance to intergranular corrosion after welding or elevated temperature exposure. The "UNS S30403" designation corresponds to the Unified Numbering System for metals, identifying a composition of 18-20% chromium and 8-12% nickel, with a maximum carbon content of 0.030%. The low carbon content is the defining characteristic of UNS
لوله های بدون درز از فولاد ضد زنگ درجه دریایی
Marine grade stainless seamless pipe refers to 316 and 316L stainless steel, the industry standard for applications requiring superior corrosion resistance in chloride-rich and marine environments. The addition of 2-3% molybdenum distinguishes this grade from 304, providing significantly enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, brackish water, and chemical environments. The seamless manufacturing process ensures uniform
1.4404 لوله های بی سیم فولاد ضد زنگ مقاومت در برابر کلرید اسید
1.4404 seamless stainless pipe is the European (EN/DIN) designation for low carbon, molybdenum-bearing austenitic stainless steel, equivalent to UNS S31603 and ASTM A312 TP316L. This grade is specifically designed for applications requiring superior corrosion resistance combined with excellent weldability, particularly where post-weld heat treatment is not practical or desired. The "1.4404" designation follows the EN 10088 and EN 10216-5 standards, which govern seamless

2205 لوله های لوله های فولاد ضد زنگ دوگانه با قدرت بالا برای کاربردهای نفت و گاز
2205 duplex stainless steel pipe is a nitrogen-enhanced duplex grade with a two-phase microstructure consisting of approximately 50% austenite and 50% ferrite. This balanced structure provides approximately twice the yield strength of standard austenitic stainless steels such as 304 and 316, combined with excellent corrosion resistance. 2205 is the most widely used duplex stainless steel grade, offering an exceptional combination of high strength, good weldability, and
لوله فولاد ضد زنگ 310S با کربن پایین و دمای بالا برای خدمات گرمای مداوم
310S pipe is a low-carbon version of the standard 310 stainless steel grade, specifically designed for continuous high-temperature service where prolonged exposure to elevated temperatures is required. The lower carbon content (0.08% maximum compared to 0.25% for standard 310) provides improved weldability and reduces the risk of carbide precipitation during welding or sustained high-temperature operation. Like its standard 310 counterpart, 310S contains high levels of
لوله های فلز ضد زنگ دوگانه ساختاری UNS S32101 لوله های نیکل پایین با قدرت بالا
UNS S32101 is a lean duplex stainless steel grade that offers a balanced combination of good strength, excellent corrosion resistance, and cost-effectiveness. It belongs to the lean duplex family (also known as LDX 2101®), containing lower nickel and molybdenum than standard duplex grades like 2205, making it a more economical alternative without significantly compromising performance. Manufactured in accordance with ASTM A789 and ASTM A790, UNS S32101 tubes are available in
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,
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
