Hello Everyone!!
Are you ready for one more exciting topic on stainless steel bars?
If yes, let’s start
In today’s topic, we will discuss about 303 austenitic stainless steel grades.
Before we start how many of you know what is austenitic stainless steel?
I think very few of you know about it!!
But don’t worry we will discuss.
Let’s start,
What is austenitic stainless steel?
Austenitic is non-magnetic stainless steel. It contains high level of chromium, nickel & low level of carbon. Because it provides high corrosion resistance & good formability austenitic stainless steel is known as widely used stainless steel.
Now let’s go on our main topic 303 austenitic stainless steel!!
What we cover in this topic?
Grade 303 is austenitic non-magnetic stainless steel with high machinability among all the other stainless steel grade.
303 have good corrosion resistance ability, excellent toughness & high strength.
Chemical Formula of 304:
Fe, <0.15% C, 17-19% Cr, 8-10% Ni, <2% Mn, <1% Si, <0.2% P, >0.15%S
303 is not hardened by heat treatment, but strength and hardness can be increased substantially by cold working, with a subsequent reduction in ductility.
