S420NL ANGLE STEEL

S420NL steel angle bar is one kind steel grade in steel standard EN 10025-3 which also contains steel grades S275N,S275NL,S355N,S355NL,S420N,S460N,S460NL.All the steel grades may be supplied in the following qualities as specified at the time of the enquiry and order: I.with specified minimum values of impact energy at temperatures not lower than -20 °C, designated as N. II. with specified minimum values of impact energy at temperatures not lower than -50 °C, designated as NL.So for angle bars S420NL shall be done low temperature impacting test under minus 50 centigrade.

Technical Requirements & Additional Services:
♦ Low temperature impacting test
♦ Rolling under standard NACE MR-0175 (HIC+SSCC)
