หลอดสี่เหลี่ยมโครงสร้าง 304 สแตนเลส สําหรับการใช้งานในอุตสาหกรรมสถาปัตยกรรม
304 stainless steel square tube is a hollow structural section with four equal sides. Grade 304 is the most commonly used austenitic stainless steel, offering an excellent balance of corrosion resistance, formability, and affordability. Our 304 square tubes are suitable for structural, architectural, and industrial applications. They are available in welded and seamless options to meet different project requirements.

ASTM A554 SS 304 ท่อสี่เหลี่ยม หนาต่อการกัดกรอบสี่เหลี่ยม
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
ASTM A554 304 316 ท่อสี่เหลี่ยมเหล็กไร้ขัด
ASTM A554 stainless steel rectangular tube is the standard specification for welded mechanical tubing made from austenitic stainless steels. Unlike pressure-rated pipes (ASTM A312), ASTM A554 tubes are designed for mechanical and structural applications where aesthetics, dimensional accuracy, and corrosion resistance are key requirements. These rectangular hollow sections (RHS) are manufactured from stainless steel strip, roll-formed into shape, and longitudinally welded. The
ASTM A554 ท่อเหล็กไร้สแตนเลสผสมท่อเหล็กไร้สแตนเลสถักหนาว
ASTM A554 stainless steel welded pipe is a standard specification for welded mechanical tubing made from austenitic, ferritic, and austenitic-ferritic duplex stainless steel. Unlike pressure pipe standards (such as ASTM A312), ASTM A554 is specifically designed for mechanical applications where appearance, mechanical properties, or corrosion resistance is required, rather than internal pressure containment. ASTM A554 Stainless Steel Pipe is manufactured from flat-rolled steel
ASTM A500 ท่อสี่เหลี่ยมจากเหล็กไร้ขัด เกรด B ผนังสี่เหลี่ยม
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
316 ท่อสี่เหลี่ยมจากเหล็กดัดเหล็ก ASTM A554 ช่องว่างสี่เหลี่ยม
316 stainless steel rectangular tubing is the premium choice for applications requiring superior corrosion resistance, especially in chloride-rich environments such as coastal areas, marine settings, and chemical processing facilities. The addition of molybdenum (2-3%) gives 316 significantly better resistance to pitting, crevice corrosion, and stress corrosion cracking compared to 304 stainless steel. This rectangular hollow section (RHS) is manufactured to ASTM A554
เกรดเรือ 316 สแตนเลสสแตนเลสทรงสี่เหลี่ยมช่องโคลนผสม 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
