The use of steel in the body ensures the component's ability to withstand high pressures, temperature variations, and corrosive environments. Overall, steel round bars play a vital role in the manufacturing of valves and fittings. Their strength, durability, and machinability make them an excellent choice for creating critical components such as valve stems, threaded connectors, and the bodies of valves and fittings.

Q: The two project is to use rebar or rebar?: It is recommended to use thread steel as far as possible, because the bonding force and holding force of the thread steel is better than that of the round steel, and it is generally known that the tensile pulling force of the round steel is relatively poor.

Q: What is the elasticity of a steel round bar?: The ability of a steel round bar to return to its original form and size after external forces or deformations is referred to as its elasticity. Steel is renowned for its high elastic modulus, indicating its resistance to deformation and ability to withstand significant stress before permanently bending or breaking. The composition of a steel round bar, specifically its carbon content and the inclusion of other alloying elements, determines its elasticity. Generally, steel with higher carbon content possesses greater elasticity and can be more easily manipulated without enduring permanent deformation. Nonetheless, it is noteworthy that factors like temperature, strain rate, and any defects or imperfections in the material can also influence the elasticity of a steel round bar.
