Physical Property Of 304/304L

Material Properties

TP304/304L is a classic austenitic stainless steel. It is renowned for its excellent corrosion resistance, high formability, and good weldability. TP304L, as a low-carbon variant, effectively suppresses carbide precipitation during welding, delivering superior resistance to intergranular corrosion. Both grades demonstrate exceptional durability across diverse industrial environments, including mild organic and inorganic acids, most atmospheric and aqueous media, and operate reliably within a broad temperature range of -196°C to 800°C. MTSCO's 304/304L seamless pipes fully comply with ASTM A312 standards. We ensure precise chemical composition compliance for every meter of pipe through rigorous PMI testing of raw materials, guaranteeing quality from the source.

Single Process Introduction: Pickling

Pickling is a critical step in enhancing stainless steel pipe quality. After heat treatment, pipes develop surface scale. We treat them with a specific acidic solution that effectively removes these oxides, along with oil residues and welding debris. Post-pickling, the pipe surface regains a uniform, silvery-white matte finish. More importantly, this process forms a dense, complete passivation protective layer on the metal surface. This protective layer significantly enhances the pipe's corrosion resistance. MTSCO strictly monitors the pickling processes at partner factories. We ensure consistent cleanliness and passivation effects on both the inner and outer walls of every TP304/304L seamless pipe. This provides reliable assurance for long-term stable operation in demanding environments such as chemical and petroleum industries.
