420 stainless pipe

420 stainless steel is a type of martensitic stainless steel and is a high-carbon grade. Under quenching conditions, it has good atmospheric resistance, certain wear resistance and corrosion resistance, and high hardness. Suitable for all types of precision machinery, bearings, electricity, equipment, instruments, meters, transportation, household appliances, food tableware, stainless steel hospital equipment, etc. It has passed the GB4806.9-2016 420 stainless steel national food safety standard test and can reach food grade standards.

Grade 420 stainless steel is a high carbon steel with a minimum chromium content of 12%. Like any other stainless steel, Grade 420 can be hardened by heat treatment. It has good ductility in the annealed state and excellent corrosion resistance when metal is polished, surface ground or hardened. This grade has the highest hardness of all stainless steel grades containing 12% chromium - 50HRC.

Stainless steel grades similar to Grade 420 include martensitic steels, other versions of Grade 420 that contain vanadium, sulfur and molybdenum in their composition, and the Grade 440 series. The carbon content of non-standard grade 420C is slightly higher than that of grade 420.

Martensitic stainless steel is a stainless steel with high hardness and high carbon content. These steels are typically manufactured using methods that require hardening and tempering. The working conditions of martensitic steels are affected by the loss of material strength at high temperatures and the decrease in ductility at negative temperatures.

product feature

420 stainless steel is a common stainless steel material whose main components are chromium and carbon. It has many unique characteristics that make it widely used in various fields.

First, 420 stainless steel has excellent corrosion resistance. Due to its high chromium content, it is able to form a dense protective film of chromium oxide, effectively preventing metal surfaces from being oxidized and corroded. Therefore, 420 stainless steel can still maintain good performance in humid, acidic or alkaline environments.

Secondly, 420 stainless steel has good mechanical properties. It has high strength and hardness and can withstand greater pressure and impact. This makes it widely used in fields such as manufacturing cutting tools, molds and mechanical parts.

In addition, 420 stainless steel also has good heat treatment properties. By adjusting the heat treatment process, its organizational structure and mechanical properties can be changed to meet the needs of different applications. This makes it an ideal material for making high-quality knives and blades.

Finally, 420 stainless steel has good processing properties. It can be formed and processed through cold working, hot working and welding processes, and can meet the needs of different shapes and sizes. This makes it widely used in manufacturing.

To sum up, 420 stainless steel is famous for its excellent corrosion resistance, good mechanical properties, excellent heat treatment properties and good processing properties. It has a wide range of applications in various fields, bringing convenience and benefits to people's lives and work.

application

Alloy 420 is used in a variety of applications requiring good corrosion resistance and excellent hardness. It is generally not used at temperatures above 800oF (427oC) due to rapid hardening and loss of corrosion resistance. Examples of applications using Alloy 420 include:

shear blade
Knives
surgical equipment
Bearing
needle valve
bushing
blade
Screen
fastener
pump shaft
step
Valve components
Steam/gas applications
Turbine
hand operated tools
