لوله های بدون درز از فولاد ضد زنگ آستنیتیک کروم منگنز UNS S20100
Chrome-manganese austenitic seamless pipe is an economical alternative to traditional chromium-nickel austenitic stainless steels such as 304 and 316. This grade achieves a stable austenitic structure by substituting a portion of expensive nickel with more cost-effective manganese and nitrogen, delivering comparable mechanical properties at a significantly lower material cost. The most common chrome-manganese austenitic grade is 201 stainless steel (UNS S20100), which
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
ASTM A554 SS 304 لوله مربعی مقاوم در برابر خوردگی بخش مربعی توخالی
What Is ASTM A554? ASTM A554 is the American standard for welded stainless steel mechanical tubing in round, square, and rectangular shapes. It is specifically designed for mechanical and structural applications – not for pressure service (use ASTM A269 or A312 for pressure). Square tubes under ASTM A554 are produced as cold-formed welded tubes from stainless steel strips, then heat-treated and finished to meet mechanical property requirements. The standard covers multiple
درجه دریایی 316 فولاد ضد زنگ قطعه مستطیل حفره ای جوش ASTM A554
Marine grade rectangular hollow section (RHS) refers to 316 stainless steel rectangular tubing specifically designed for applications in coastal, offshore, and marine environments where standard 304 stainless steel would be susceptible to pitting and corrosion from chloride exposure. The addition of 2-3% molybdenum to the 316 grade provides significantly enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, salt spray, and chloride-rich
لوله بی سیم فولاد ضد زنگ با نیکل کم برای محیط های ساختاری تزئینی خوردنی
Low-nickel stainless steel seamless tube is an economical alternative to traditional austenitic stainless steels such as 304 and 316. By reducing nickel content and increasing manganese and nitrogen, this grade achieves a balanced austenitic structure at a significantly lower material cost, making it an attractive choice for general industrial applications where extreme corrosion resistance is not the primary requirement. The most common low-nickel austenitic grade is 201
آستنیتیک مقاومت در برابر خوردگی Hastelloy C-22 آلیاژ نیکل برای پردازش شیمیایی خشن
Hastelloy C-22: Ultimate Corrosion-Resistant Nickel Alloy Hastelloy C-22 is a fully austenitic, advanced corrosion-resistant nickel-chromium-molybdenum-tungsten alloy. It offers outstanding resistance to both uniform corrosion in oxidizing media and localized attack (pitting, crevice corrosion) in reducing environments. Unlike standard alloys, C-22 provides exceptional resistance to stress corrosion cracking (SCC), intergranular attack, and weld heat-affected zone (HAZ)
ASTM A500 لوله مربع فولاد ضد زنگ درجه B بخش ساختاری مربع سوراخ
What Is ASTM A500? ASTM A500 is the American standard for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the go-to specification for structural applications where strength, weldability, and economy are required. Square steel tubes under ASTM A500 are produced as cold-formed welded tubes, then heat-treated to remove internal stresses and improve mechanical properties. The standard covers four grades: A, B, C, and
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)
لوله بدون درز کروم منگنز آستنیتی کم نیکل جایگزین برای کاربردهای صنعتی
Chrome-Manganese Austenitic Seamless Pipe with Mill Test Certificate The Chrome-Manganese Austenitic 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
