Steels shall be fully killed. NOTE This excludes the use of rimming, balanced or semi-killed steel. 7.2 Tube manufacture and delivery conditions 7.2.1 The tubes shall be manufactured from strip by electric welding. The tubes shall not contain strip end welds. Possible surface conditions are: a) S1 (black); b) S2 (pickled); c) S3 (cold rolled); d) S4 (coated to an agreed condition). The surface conditions S1 and S3 apply for the strip. The surface condition S2 and S4 can apply for the strip or the tube; the purchaser should, where necessary, indicate the required condition at the time of enquiry and order. 7.2.2 Tubes made of the steel grades E155, E195, E235, E275 and E355 shall be supplied in one of the delivery conditions given in Table 1, except +CR2. Tubes made of the grades E190, E220, E260, E320, E370, E420, E460, E500, E550, E600 and E700 shall be supplied in the delivery condition +CR2. SIST EN 10305-5:2016
