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

Automotive Precision Seamless Alloy Steel Pipe (SCM415 / SCM420 / SCM430 / SCM435 / SCM440) Material This product is a precision seamless mechanical steel pipe manufactured from JIS SCM-series chromium–molybdenum (Cr-Mo) alloy steels . These steels are widely used for automotive and high-load mechanical parts because they combine high strength, good hardenability, fatigue resistance, and stable machining performance . Chemical composition requirements for SCM415/420/430/435

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

Low Fin Tubes Stainless Steel Integral Low Finned Tube for Industrial Heat Exchangers Material This product is an integral low finned tube manufactured from high-quality stainless steel . The fins are formed directly from the parent tube material through a cold-forming process, ensuring metallurgical continuity between the tube and fins. This construction provides excellent corrosion resistance, high structural integrity, and long-term reliability in demanding industrial heat
