DIN 17440 Grade X2CrNiMoN17-13-5 solution heat-treated and quenched

DIN 17440 Grade X2CrNiMoN17-13-5 solution heat-treated and quenched introduction

Properties:
- high resistance to pitting corrosion and intergranular corrosion (better than 1.4436)
- resistant to crack corrosion, with highest general resistance to many organic acids of high concentration and temperature, e.g. in not oxidizing acids and chloride containing media (sea water), also in inorganic and mixing acids
- application temperature: -200 to 550 °C
Application:
- in reactor industry, marine engineering, chemical industry
- for construction of pressure tanks suitably
