Alloy 20 ( Carpenter 20 ) is an austenitic stainless steel possessing excellent resistance to hot sulfuric acid and many other aggressive environments which would readily attack type 316 stainless.
12.
Candidate materials that meet these property and performance goals include incumbent alloys in power generation, such as nickel-based superalloys for turbomachinery components and austenitic stainless steels for piping.
13.
The combination of increased wear and fatigue resistance with retention of corrosion resistance and non-magnetic properties of austenitic stainless steels has already resulted in a lot of applications in the last 20 years
14.
The high nickel and molybdenum contents of the AL-6XN alloy give it good resistance to chloride stress-austenitic stainless steels, and thereby often allows it to be used in thinner sections.
15.
Austenitic stainless steels at atmospheric conditions have excellent corrosion resistance to water and various chemicals; however, wear resistance and hardness are low and they can not be hardened by conventional heat treatment methods.
16.
:It is my understanding that austenitic stainless steel, which is normally nonmagnetic, can be magnetic if it has been " cold worked " . talk ) 15 : 53, 27 December 2007 ( UTC)
17.
It has strength / modulus of elasticity ratios almost twice those of 18-8 austenitic stainless steel, larger elastic deflections in springs, and reduced force per unit displacement 2.2 times below those of stainless steel appliances.
18.
However, most non-ferrous metals, like alloys of copper, aluminum, or nickel, and some high alloy steels such as austenitic stainless steel ( 304, 316 ), produce an opposite effect when these are quenched : they soften.
19.
"' Kolsterising "', or "'Kolsterizing "', is a surface hardening treatment for austenitic stainless steel, nickel, and cobalt-chrome alloys producing increased mechanical and wear properties without adversely affecting corrosion resistance.
20.
Argon-oxygen blends with 1 2 % oxygen are used for austenitic stainless steel where argon-CO 2 can not be used due to required low content of carbon in the weld; the weld has a tough oxide coating and may require cleaning.
