SOLEIL A2 Steel

SOLEIL A2 Steel

Steel name: SOLEIL A2
Diagram No.: 2477
Mat.No. (Wr.Nr.) designation: 1.4006
DIN designation: X12Cr13
ASTM designation: A240 TP410
UNS designation: UNS S41000
Chemical composition in weight %: 0.12% C, 0.40% Si, 0.50% Mn, 12.50% Cr
Steel group: Martensitic stainless steels
Properties: SOLEIL A2 has combined chromium (about 13%) and carbon (about 0.10%) additions to provide an excellent combination of high mechanical properties and improved corrosion resistance properties. The grade has a martensitic microstructure. The final mechanical properties may be optimised by selecting an appropriate heat treatment. In the annealed conditions the alloy presents ductility and may be formed. Chromium additions (about 13%) improve the corrosion resistance, particularly in wet conditions when compared to C-Mn steels. Slightly acidified and abrasion conditions are considered.
Applications: The main applications concern mechanical industry, oil and gas industry, sugar industry and constructional components.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 950 - 1000°C (1742 - 1832°F), oil or air cooling.
Tempering: 250°C or 600 - 780°C (1112 - 1436°F), air cooling. (optimised depending on requested mechanical properties). Tempering heat treatment performed in the 300 - 600°C (572 - 1112°F) temperature range will be avoided because it results in higher susceptibility to stress corrosion attack and embrittlement. Time/temperature conditions in the 600 - 780°C (1112 - 1436°F) will be optimised in order to obtain the requested ductility/ hardness compromise. The maximum annealing conditions are obtained with a heat treatment at 900 - 950°C (1652 - 1742°F) followed by low cooling rate.
