Carbon Steel Octagonal Ring Joint Gasket with PTFE Coated - RTJ 301-CS
RTJ 301-CS is made of carbon steel and then PTFE coated to avoid rush. Carbon steel octagonal ring joint gasket with PTFE coated price is much cheaper than stainless steel such as SS 304, SS 316L, so it is a economical choice for ring type joint flanges.What is Carbon Steel?
Steel is commonly considered carbon steel when no minimum content is specified for any alloying element (for example, aluminum, chromium, nickel, molybdenum, vanadium, etc.) or any other element added to obtain a desired alloy effect. The manganese does not exceed 1.65%, the specified minimum for copper does not fall below 0.40% or exceed 0.60% and silicon does not exceed 0.60%.Carbon content within carbon steel bars alters the characteristics of steel, having higher tensile strength. Depending on its carbon content, the increase in carbon will raise carbon steel’s hardness and strength. Mild carbon steel can be bent, cut, and twisted to easily create desired shapes compared to other metals. A hard carbon steel bar is commonly used for knife blades or applications that need strength and hardness but not flexibility. For these reasons, carbon steel bar is ideal for many industrial products and applications where durability is essential.Carbon Steel Levels are Divided as Follow
Low Carbon CS = 0.06% to 0.25% carbon contentMedium Carbon CS = 0.25% to 0.55% carbon content
High Carbon CS= > 0.55% to 1.00% carbon content
Ultra-high-carbon steel: approximately 1.25 to 2.0% carbon content
