06Cr19Ni10 pressure vessel forged cylinder
The 06Cr19Ni10 pressure vessel forged cylinder we manufacture is a high-performance austenitic stainless steel forging, engineered for demanding pressure vessel applications. Manufactured in compliance with GB/T national standards, it is fully interchangeable with international equivalents such as ASTM 304 / AISI 304 / EN 1.4301 / SUS304. This forged cylinder offers excellent corrosion resistance, superior mechanical strength, and high reliability under extreme operating conditions.
As a critical component in pressure systems – including chemical reactors, heat exchangers, boilers, storage tanks, and high-pressure pipelines – the 06Cr19Ni10 forged cylinder delivers the durability and reliability required for long-term safe operation in harsh industrial environments. The material can be used within a temperature range of -196°C to 800°C, making it suitable for both cryogenic and high-temperature service.

Key Features & Advantages
Superior Corrosion Resistance
The 06Cr19Ni10 austenitic stainless steel forging exhibits excellent resistance to oxidizing acids, alkaline solutions, organic acids, as well as atmospheric, water, and steam corrosion. Its stable austenitic structure and high chromium‑nickel content provide a robust passive oxide layer that protects against aggressive chemical environments.
01
High Mechanical Strength Under Pressure
With a minimum tensile strength of 520 MPa and yield strength of 220 MPa, the 06Cr19Ni10 forged cylinder is engineered to withstand extreme pressure loads commonly encountered in ASME Section VIII, GB/T 150, and other international pressure vessel codes. The forging process refines the grain structure and eliminates internal voids, resulting in superior isotropy and fracture resistance.
02
Broad Operating Temperature Range
Suitable for service from cryogenic temperatures ‑196°C up to 800°C, the 06Cr19Ni10 forged cylinder maintains excellent toughness and structural stability across a wide thermal spectrum, making it ideal for both LNG storage facilities and high-temperature chemical reactors.
03
Excellent Weldability and Formability
The low carbon content (≤0.08%) minimizes carbide precipitation during welding, reducing the risk of intergranular corrosion in the heat‑affected zone. The material also exhibits outstanding cold‑forming capabilities, allowing for secondary fabrication and assembly without compromising mechanical integrity.
04
Full Compliance with International Standards
Every 06Cr19Ni10 pressure vessel forged cylinder is manufactured and tested in strict accordance with GB/T 150, NB/T 47010-2017, ASME SA-182, ASTM A182, and PED (2014/68/EU) requirements. Third‑party inspections and certifications are available upon request.
