P91 metal welding refers to welding techniques used for joining P91 steel, a type of high-strength, low-alloy steel commonly used in high-temperature applications.

• P91 steel is a type of low-alloy steel known for its high strength and creep resistance.

• Welding P91 steel requires preheating and post-weld heat treatment to prevent cracking and maintain mechanical properties.

• Common welding techniques for P91 steel include TIG (tungsten inert gas) welding and SMAW (shielded metal a...read more

Calibration is the process of comparing measurements of an instrument or device to a known standard to ensure accuracy.

• Calibration involves adjusting the instrument or device to align with the standard

• It is important for maintaining accuracy and reliability of measurements

• Calibration is typically done regularly to ensure consistent performance

• Examples include calibrating thermometers, scales, and pressure gauges

The percentage of carbon in MS (mild steel) typically ranges from 0.05% to 0.25%.

• Percentage of carbon in MS (mild steel) is usually between 0.05% to 0.25%.

• Carbon content affects the strength and hardness of the steel.

• Higher carbon content results in harder but more brittle steel.

• Lower carbon content results in softer but more ductile steel.
