 JIS G 3445 Grade STKM 13C Seamless Steel Tube, also known as mild steel pipes and tubes.  STKM 13C Tubes are low-cost Low Carbon Steel Tubes with max 025% carbon content that are easy to form and shape. These pipes are manufactured as per JIS Specification and commercially referred to as cds pipes or ms pipes. STKM13C seamless steel tubes are high-quality carbon steel pipes manufactured under the Japanese Industrial Standard (JIS G3445). Designed for mechanical and structural applications, these tubes combine exceptional strength, dimensional accuracy, and cost-efficiency, making them ideal for: Automotive chassis components Hydraulic cylinder barrels Industrial machinery frameworks Agricultural equipment STKM13C Seamless Steel Tubes Precision Engineered for Durability & Performance Standard Grade Chemical Components (%) Mechanical properties （Bright Annealing) C Si Mn P S Cr Ni Cu Tensile Strength (Mpa) Yield Strength (Mpa) Elongation (%) JIS G3445 STKM 13C 0.2 0.21...

 E355 Hydraulic steel tube, as the core transmission components of hydraulic systems in construction machinery, mining equipment, and aerospace, directly determine the safety and service life of the equipment. I. Raw Materials selections: I. Materials Science: The Foundation of High-Precision Hydraulic Tubes High-precision hydraulic tubes are made from cold-drawn seamless steel tubes (material grades: ST52.4/30CrMo/SAE 4130), with a yield strength of ≥500MPa and an elongation of ≥15%, ensuring resistance to deformation under high-pressure conditions. 2. Material Pre-treatment Process Phosphating and Saponification Treatment: Before cold drawing, the tube blanks undergo surface phosphating (ZnCaPO₄ coating) to reduce the friction coefficient. A saponification layer (sodium stearate) further lubricates, ensuring uniform wall thickness after cold drawing (tolerance ±0.1mm). II. Precision Processing Flow: Five Core Procedures 1. Cold Drawing Forming Process Die Design: Multi-stage ...

 When sourcing precision honed tube supplier for hydraulic cylinders, mining equipment, or industrial machinery, partnering with a reliable Chinese manufacturer can significantly reduce costs while ensuring quality. However, not all suppliers meet the stringent technical and logistical demands of global clients. As a ISO 9001-certified honed tube factory with 35+ years of export experience to North and South America, ANBAO GROUP reveal the critical criteria to evaluate suppliers – and why our solutions outperform competitors. 1. Precision Engineering That Meets Global Standards A superior honed tube requires ≤30μm inner diameter tolerance and Ra 0.2μm surface roughness to minimize oil leakage and piston wear. Our factory employs: Advanced CNC honing machines with laser-guided straightness control 100% inline inspection using Mitutoyo CMM and surface profilometers E355 ST52 grade steel with optional chrome plating (20-50μm thickness) 2. Produc...

Honed barrel tube  is well known as hydraulic cylinder tube in many industries. This is because honed tubes are the most important materials of manufacturing hydraulic cylinders. And as this kind of tubing is usually honed in tube inside diameter, it is known as honed ID tubing also. The honed cylinder tube suitable for various kinds of Precision Mechanical Tubes,Hydraulic Cylinder Tube and Pneumatic Cylinder Tubes, Stainless Steel Cylinder Tubing, Construct use Multi Joint Tube, Steel Axis Pipe, Injection Machine and Robotic Arm. Quality Standards: DIN 2391 Seamless Precison Steel Tubes EN10305 Steel Tubes for Precision Applications Seamless Cold Drawn Tubes ASTM A519 Standard Specification for Seamless Carbon and Alloy Steel Mechanical Tubing JIS G3445 Carbon Steel Tubes for Machine Structural Purposes Grade: ST 52, ST52.3, CK45, E355, 16Mn, STKM13C , SAE1020, SAE1026, SAE1045 Delivery Condition: BK, BK+S, GBK, NBK ID Size : 20mm – 1500mm Length: max...
