Stainless Steel 440C Pipes are high-carbon martensitic stainless steel, known for their exceptional hardness, wear, and corrosion resistance. They offer superior strength and toughness with a high carbon content, making them suitable for applications in harsh environments, such as cutlery, bearings, and surgical instruments. Stainless steel 440C pipes are heat-treatable and can achieve high hardness levels, making them resistant to abrasion and corrosion. They are often utilized in industries requiring durable and high-performance stainless steel components subjected to extreme wear and friction.

We offer These Stainless Steel 440C Pipes as per DIN, ISO, JIS or ANSI Standard.
Stainless Steel 440C Pipes applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Stainless Steel 440C Pipes are sized primarily based on nominal pipe size (NPS) and schedule. NPS indicates the nominal reference size, while the schedule denotes the thickness of the pipe wall. These pipes adhere to industry standards for dimensions and are available in various sizes and schedules to accommodate different applications and pressure requirements. Size selection depends on factors like intended use, flow requirements, and structural considerations.
Stainless Steel 440C pipes, being a high-chromium martensitic stainless steel, exhibit excellent resistance to corrosion in many environments. However, they can still be susceptible to galvanic corrosion when in contact with dissimilar metals in certain electrolyte conditions. To mitigate this risk, proper material selection and insulation measures should be employed, such as using compatible metals or implementing insulating materials to prevent direct contact between dissimilar metals. Regular inspection and maintenance are also essential to identify and address any corrosion issues promptly.
Stainless Steel 440C pipes can be used for natural gas applications, but it’s essential to consider factors such as pressure, temperature, and local regulations. While Stainless Steel 440C offers excellent corrosion resistance and high strength, its use for natural gas transmission and distribution may depend on specific project requirements and industry standards. Consulting with engineers and adhering to relevant codes and standards, such as ASME B31.8 for gas transmission and ASTM A312 for stainless steel pipes, can help ensure the suitability and safety of Stainless Steel 440C pipes for natural gas applications.
Stainless Steel 440C pipes can be used for underground applications, but several factors need consideration. While Stainless Steel 440C offers excellent corrosion resistance, it’s essential to assess the soil conditions, potential for abrasion, and risk of external damage from factors like excavation or heavy machinery. Additionally, proper installation techniques, including backfilling with suitable materials and corrosion protection measures, such as coatings or cathodic protection, are crucial to ensure the long-term integrity and performance of Stainless Steel 440C pipes underground. Consulting with engineers and adhering to relevant industry standards and regulations, such as ASTM A790 for seamless and welded ferritic/austenitic stainless steel pipe, can help guide the selection and installation process for underground applications.
