SAE J526 Welded Low-Carbon Steel Tubing (ERW) — Precision Steel Tube for Automotive Material SAE J526 tubing is electric-resistance-welded (ERW), single-wall, low-carbon steel precision tubing designed for automotive and similar industrial uses where reliable pressure performance and controlled forming (bending, beading, brazing, and double flaring) are required. The tube is formed from a single steel strip; after welding, the outside weld bead is removed to provide a smooth

904L Stainless Steel Seamless Tubing (Austenitic Stainless Steel Tube for Chemical Industry) Material 904L (UNS N08904 / EN 1.4539) is a super austenitic, low-carbon stainless steel alloyed with high Nickel (Ni) and Molybdenum (Mo) plus Copper (Cu) . This chemistry is designed for aggressive chemical service , especially where reducing acids (e.g., sulfuric acid) and chloride-containing media are concerns. Specifications Product : Seamless tubing (cold-worked or hot-finished;

410 Stainless Steel Seamless Pipe (Martensitic) for Automotive Parts Material Overview 410 is a basic martensitic stainless steel (≈12% Cr class) designed for applications that need higher strength, wear resistance, and moderate corrosion resistance compared with carbon steels. It is commonly supplied annealed or quenched & tempered to reach targeted hardness/strength levels for machined automotive components. Specifications Product type: Martensitic stainless steel seamless

Manganese Steel Pipe – Carbon Steel Precision Seamless Pipe for Drilling Engineering Material This product is a carbon–manganese (C–Mn) steel precision seamless pipe designed for drilling and harsh field operations. Compared with plain carbon steel, controlled manganese content improves strength, hardenability, and impact toughness, making the tube body more reliable under cyclic load, vibration, and abrasive media commonly found in drilling engineering. Typical grade options

Electropolished 316L Stainless Steel Precision EP Pipe for Semiconductor (UHP) Systems Material This product is a precision stainless steel pipe/tubing made from 316L austenitic stainless steel (low-carbon, Mo-alloyed) and finished by electropolishing (EP) —primarily on the internal wetted surface —to achieve an ultra-smooth, contamination-resistant surface for semiconductor high-purity and ultra-high-purity (HP/UHP) gas and chemical delivery lines. Specifications Grade :

STKM 13A Carbon Steel Seamless Precision Tube (Thick-Walled) for Mechanical Engineering Material STKM 13A is a JIS-grade carbon steel tube designed for machine-structural and general mechanical parts. As a seamless precision tube, it is commonly produced by hot-finished seamless tubing followed by cold working (e.g., cold drawing) to achieve improved dimensional accuracy, surface finish, and consistency—especially important for thick-walled load-bearing components and

ASTM A513 4130 Chromoly Cold Drawn Alloy Steel Precision (DOM) Tube / Pipe for Mechanical Engineering Material This product is ASTM A513/A513M Grade 4130 chromium–molybdenum (Chromoly) mechanical tubing manufactured by the ERW → Drawn-Over-Mandrel (DOM) → cold drawing route. ASTM A513 Type 5 DOM tubing is produced from electric-resistance-welded tube that is subsequently cold drawn over a mandrel to achieve high dimensional accuracy, improved concentricity, and a smooth bore

Crimped Fin Tube (Helically Tension Wound, Cold-Formed Finned Tube) for Air Coolers Material A Crimped Fin Tube (also called a Spiral Tension Wound / Cold-Formed Finned Tube ) is a heat-transfer tube where a metal fin strip is helically wound under controlled tension onto a base tube . The fin strip is pre-formed to widen the contact “foot,” then mechanically locked to the tube surface (with end fixing such as tack/tag welding or spot welding depending on design). Common
