1.4307 لوله بدون درز فولادی ضد زنگ EN DIN درجه آستنیتی کم کربن
1.4307 seamless stainless pipe is the European (EN/DIN) designation for a low carbon austenitic stainless steel grade, equivalent to UNS S30403 and ASTM A312 TP304L. This grade is specifically designed for applications requiring excellent corrosion resistance combined with superior weldability, particularly where post-weld heat treatment is not practical or desired. The "1.4307" designation follows the EN 10088 and EN 10216-5 standards, which govern seamless stainless steel
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
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
لوله TP316L SMLS لوله بدون درز با مولی بدن کم کربن
TP316L SMLS pipe is a low carbon, molybdenum-bearing austenitic seamless stainless steel pipe designed for superior corrosion resistance in aggressive environments. The "TP" designation indicates that the pipe meets the requirements of ASTM A312, the standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes. "SMLS" denotes seamless construction, meaning no longitudinal weld seam exists. The low carbon content (0.030% maximum)
Super Duplex 2507 ورق فولاد ضد زنگ ASTM A240 مقاوم به خوردگی با قدرت بالا
ASTM A240 Super Duplex 2507 (UNS S32750) is a high-strength, corrosion-resistant stainless steel plate with a ferritic-austenitic microstructure. It offers approximately three times the yield strength of 316L and a PREN value of 40 or higher, providing exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Ideal for the most demanding environments, Super Duplex 2507 is widely used in offshore platforms, chemical processing, seawater

S32750 Super Duplex Tube ASTM A790
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.
