Dear
ASTM A333 and ASTM A106 are both carbon steel pipe specifications, but they serve different purposes and have distinct characteristics.
ASTM A333 pipes are designed for low-temperature service, typically below -50°F (-45°C). They are made from low-temperature carbon steel and are suitable for applications where the pipes will be exposed to cold temperatures.
ASTM A106 pipes, on the other hand, are suitable for high-temperature service and are often used in power plants, refineries, and other high-temperature applications.
The main differences between A333 and A106 pipes are:
1.Temperature range: A333 pipes are designed for low temperatures, while A106 pipes are suitable for higher temperatures.
2. Material composition: A333 pipes have a specific chemical composition that ensures low-temperature toughness, while A106 pipes have a different composition that prioritizes high-temperature strength.
3. Mechanical properties: A333 pipes have specific requirements for impact testing and notch toughness, which are not required for A106 pipes.
Regarding SA 333 Gr.6 pipes below 2" in hot-finished condition, it's possible to supply them in this condition. However, it's essential to verify the specific requirements of your project or application to ensure compliance.
In terms of chemical composition and mechanical properties, low-temperature CS steel pipes like A333 typically have:
1)Lower carbon content to improve toughness
2)Specific requirements for manganese, silicon, and other elements to enhance low-temperature properties
3)Impact testing requirements to ensure toughness at low temperatures
A106 pipes, on the other hand, prioritize high-temperature strength and may have different chemical composition and mechanical property requirements.
Your experience with these pipes will depend on your specific application and industry.

Is there below 2'' pipe of material SA 333 Gr.6 supply in hot finish condition?--On Tuesday, October 26, 2010 at 11:01:33 AM UTC+5:30 Martin Prad wrote:Hi,
What is the real difference of ASTM A333 pipe from ASTM a106grB?
ASTM A333 is a low temperature CS pipe but 106 is not. What is the main features of Low temperature CS steel pipes by their chemical composition and mechanical properties?
Please share your experience on this.
Martin.
