1) Remark: high stength quenched and tempered fine grain steel N-A-XTRA 70 for forming, weldable Application: in range of -60°C to 350°C - for pressure tanks according to TRB 100 and AD-Merkblatt W 1, W 10, HP 8/1 - in nuclear technologies with considering the nuclear techniques rules and object applied specifications Smelting: - oxygen blowing process - electric arc process - removing oxygen state: especially becalmed - if danger for stress corrosion because the application, so look for retaliatory action
