A312 TP310H BE Austenitic Stainless Steel Pipe 1 - 48 Inch For Surgical Instrument

A312 TP310H BE Stainless Steel Seamless Pipe For Surgical Instrument

A312 TP 310H is a low-carbon, nitrogen-enhanced version of Type 3170H austenitic sta

inless steel. The Type 317alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. The nitrogen in Type 317LN adds additional resistance to sensitization in some circumstances.

The nitrogen content of Type 310H stainless steel also provides some solid solution hardening, raising its minimum specified yield strength compared to Type 310H stainless steel. Like Types 310 and 310H the Type 310H alloy also offers good resistance to general corrosion and pitting/crevice corrosion.

Fatigue Resistance

The fatigue strength or endurance limit is the maximum stress below which a material is unlikely to fail in 10 million cycles in an air environment. For austenitic stainless steels as a group, the fatigue strength is typically about 35 percent of the tensile strength. However, substantial variability in service results is experienced since additional variables such as corrosive conditions, type of loading and mean stress, surface condition, and other factors affect fatigue properties. For this reason, no definitive endurance limit value can be given which is representative of all operating conditions.

Stress Corrosion Cracking

Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Although the ATI 316, ATI 316L and ATI 317Ti alloys are more resistant to SCC than the 18 Cr-8 Ni alloys, they still are quite susceptible. Conditions that produce SCC are:

(1) Presence of halide ion (generally chloride),

(2) Residual tensile stresses, and

(3) Temperature in excess of about 140°F (60°C)

Stresses result from cold deformation or thermal cycles during welding. Annealing or stress relieving heat treatments may be effective in reducing stresses, thereby reducing sensitivity to halide SCC. Although the low carbon ATI 316L and ATI 316LN alloys offer no advantage as regards SCC resistance, they are better choices for service in the stress relieved condition in environments which might cause intergranular corrosion. If SCC resistance is desired, use of duplex stainless steels such as ATI 2205™ or ATI 2003® duplex stainless alloys should be considered.
