UGIMA® 4362 Hot Rolled, Solution Annealed
UGIMA® 4362 Hot Rolled, Solution Annealed introduction
UGIMA® 4362 is an austeno-ferritic stainless steel (Duplex) with better machinability than a standard 1.4362 (UGI® 4362), due mainly to reduced tool wear and better chip breakability.
UGIMA® 4362 complies with the specification of 1.4362 in accordance with EN 10088-3, but retains all the qualities of UGI 4362, namely:
Higher mechanical properties (Rm and Rp0.2) than those of a standard 1.4404 (316L), or even a 1.4406 (316LN)
Corrosion resistance greater than or equal to that of a standard 1.4404 (316L).
UGIMA®4362 exhibits good mechanical properties: its tensile strength and yield strength are therefore significantly higher on bars than those of a standard 1.4404.
In addition, this partially ferritic grade has a ductile-fragile transition temperature which, in the case of large-section bars, restricts its use to low-temperature applications
The chemical composition of UGIMA®4362 is optimised to obtain a two-phase structure containing between 45% and 70% ferrite after solution heat treatment between 950°C and 1050°C followed by rapid cooling.
The low Mo content makes the grade far less susceptible than 1.4462 to the precipitation of embrittling intermetallic phases (sigma, X). The sigma phase therefore only appears after holding at 700°C for 20 hours.
However, as for UGI 4362, precipitation of the ' phase at between 350°C and 550°C in UGIMA® 4362 may lead to an embrittlement of the structure. Consequently, the temperature at which UGIMA® 4362 is used must be limited to 300°C.
Equivalent material: DIN 1.4362, DIN X2CrNiN23-4, UNS S32304, ASTM S32304, ISO 4362-323-04-I, ISO X2CrNiN23-4, EN 1.4362, EN X2CrNiN23-4
