Stainless steel 446 rods vs 310
The ASTM A276 stainless steel 446 rods have ferritic microstructure with high Chromium content that shows excellent oxidation and corrosion resistance. They are heat resistant too, especially with molten copper and brass, unlike any other stainless steel grades. They work best in high-temperature applications between 1500°F to 2100°F. Hence, they find maximum use in furnaces, boilers, burners, etc.
The 310 stainless steel has an austenitic microstructure with high amounts of carbon in them. They cannot be hardened by heat, unlike UNS S44600 hot rolled bar. They are great for high-temperature applications around 1150°C. Hence, they find applications in furnaces, thermowell, petroleum refining, steam boilers, etc.

What is a stainless steel 446 forged bar?
The ASTM A276 GR 446 forged bar belongs to the ferritic stainless steel category with high chromium content. The 446 stainless steel is heated to 2050°F with further cooling and annealing to produce the 446 forged bars.
Forging increases the stability of the material at very high temperatures as high chromium content usually leads to deformation with more heat. They also have great oxidation and corrosion resistance. Hence, they find great uses in furnaces, boilers, railway components, automotive, etc.
446 steel cold finished bars and 446 SS hex bar offers a variety of shapes and sizes ranging from 16mm to 130mm.
SS 446 cold rolled vs hot rolled bar
The ASTM A276 type 446 cold rolled round bars are formed after the material undergoes a hot rolling process. They have high tolerance and smooth surface finish. Hot rolling process of 446 bars occurs at around 1000°F. It improves the toughness, strength and weldability of the material. You can shape them easily at such high temperatures.
What are ASTM A276 type 446 cold finished bars?
When cold rolled steel is processed further, it forms 446 steel cold finished bars. The cold drawing of hot-rolled bars is done through a die. It improves the surface finish and dimensional tolerances of the material. The cold finished bars have great industrial applications.
