ASME SA335 P23 Pipe is a low-alloy chromium-molybdenum seamless pipe manufactured according to ASTM A335/ASME SA335 specifications for high-temperature and high-pressure applications. Also known as ASTM A335 P23 Alloy Steel Seamless Pipes, this grade contains chromium, tungsten, vanadium, niobium, and molybdenum, offering excellent creep strength, oxidation resistance, and long-term durability in power generation, petrochemical, and boiler systems. P23 material is commonly identified as UNS K40712 Pipe and 2.25Cr-1.6W-V-Nb Pipe, making it a preferred choice for modern thermal power plants and heat exchanger systems.

ASTM A335 P23 Alloy Steel Seamless Pipes – Overview

We are a trusted ASTM A335 Grade P23 Alloy Steel Seamless Pipes Manufacturer, Exporter & Suppliers serving customers across India and international markets. Our pipes are manufactured to stringent quality standards and are designed to perform reliably in demanding environments involving elevated temperatures and pressures.

ASTM A335 P23 Pipe belongs to the family of ferritic alloy steel pipes developed specifically for high-temperature service. The addition of tungsten, vanadium, and niobium improves creep rupture strength and enhances the material’s long-term stability under thermal stress.

Industries worldwide prefer A335 P23 Chrome Pipe because it delivers an excellent balance of mechanical strength, weldability, corrosion resistance, and thermal efficiency. These properties make it suitable for critical installations where operational safety and service life are essential.

What is ASTM A335 P23 Pipe?

ASTM A335 P23 Pipe is a seamless ferritic alloy steel pipe designed for elevated temperature applications. It is widely used in:

• Thermal power plants
• Superheater systems
• Reheater tubes
• Boiler piping systems
• Petrochemical processing plants
• Oil and gas refineries
• Heat exchangers
• Pressure vessels
• Steam pipelines

The material designation UNS K40712 Pipe refers to a low-alloy steel composition containing approximately 2.25% chromium and tungsten-based strengthening elements. Due to its superior creep resistance, P23 has become a modern alternative to conventional alloy steel grades used in power generation facilities.
