Sanicro® 28 is a multi-purpose austenitic stainless ELC alloy for service in highly corrosive conditions. It is characterized by:
Status according to EN 10 204 3.1
Round-cornered square, as well as round billets, are produced in a wide range of sizes according to the following tables. Larger sizes offered on request.
Unground, spot ground or fully ground condition.
Peel turned or black condition.

Seamless tube and pipe
Sanicro® 28 conforms to the mechanical properties according to specification EN 10088-3.
Testing is performed on separately solution annealed and quenched test pieces.

a) Rp0.2 corresponds to 0.2% offset yield strength.
b) Based on L0 = 5.65√S0 , where L0 is the original gauge length and S0 the original cross-sectional area.
Due to its austenitic microstructure, Sanicro® 28 has very good impact strength, both at room temperature and at cryogenic temperatures.
Tests on bar have demonstrated that the steel fulfils the requirements according to the European standards EN13445-2(UFPV-2)(min.60J(44ft-lb)at-270oC(-455oF))andEN10272(min.60J(44ft-lb)at-196oC.(-320oF).
