Ikhtisar Produk
ItuASTM A312 304 Pipa Baja Tahan Karat Mulus is a premium-grade, high-performance pipe manufactured to the rigorous requirements of ASTM A312 — the standard specification for seamless and welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. Produced from high-quality 304 baja tahan karat (UNS S30400), this pipe offers exceptional corrosion resistance, excellent mechanical properties, and reliable performance in demanding industrial environments. The seamless construction eliminates weld seams, providing superior strength, pressure integrity, and resistance to stress corrosion cracking compared to welded alternatives. Available in custom sizes with outer diameters from Φ3mm to Φ114mm (seamless) and wall thicknesses from 0.2mm to 4.5mm, this pipe can be further processed with bending, pengelasan, cutting, punching, and uncoiling services to meet specific project requirements. With a wide range of surface finishes (2B, 8K, BA, HL, No.4, No.1, 1D, dll.) and multiple international standard compliance (ASTM, DIA, AISI, GB, DARI, DI DALAM), this pipe is the trusted choice for chemical processing, minyak & gas, farmasi, food processing, pembangkit listrik, and nuclear applications.

Pertanyaan Umum
Q1: What is the difference between ASTM A312 and ASTM A269?
A: ASTM A312 is the specification for seamless and welded austenitic stainless steel pipe intended for high-temperature and general corrosive service, suitable for transporting high-pressure fluids and gases in industrial piping systems. ASTM A269 is a standard primarily for stainless steel tubing used in sanitary and instrumentation applications; it offers greater dimensional precision and is typically used for smaller diameters and tighter tolerances.
Q2: What is the difference between 304 and 304L stainless steel?
A: 304L is the low-carbon version of 304 (carbon content ≤0.03% vs. ≤0.08% for 304), offering superior resistance to intergranular corrosion (resistance to sensitization) after welding. 304 possesses slightly higher tensile and yield strengths. For most general corrosive applications, 304 is sufficient; Namun, 304L is the better choice for applications involving extensive welding or highly corrosive environments.
Q3: What is the difference between seamless and welded steel pipe?
A: Seamless steel pipe has no weld seam, offering superior pressure integrity, burst resistance, and resistance to stress corrosion cracking; it is suitable for high-pressure and critical applications. Welded steel pipe is more cost-effective and available in a wider range of sizes, making it suitable for general industrial applications. This product is available in both seamless and welded options.
Q4: What is the difference between 2B, 8K, and BA surface finishes?
A: 2B is a cold-rolled finish with a moderate sheen; it is the most common industrial finish. 8K is a mirror-polished finish with high reflectivity, suitable for decorative and sanitary applications. BA is a bright-annealed finish with a uniform, smooth sheen, suitable for applications requiring a clean surface.
