| 1) Remark: Non-stabilized austenitic steels of grade A4 are "acid proof steels", which are Mo alloyed and give a considerably better resistance to corrosion (boiling sulfuric acid, to a certain extent to chloride containing environment). Lower limit of operational temperature for headless screws: -200 °C Application: cellulose industry, food industry, shipbuilding, bolts and nuts acc. to DIN 267-13 |
