Material Information Sheet For Plates: Erndtebrücker Eisenwerk

This document provides material information for steel plates that can be L290 or X42 under API 5L 44th Edition and ISO 3183:2007 standards. It specifies the delivery conditions, heat and product analysis requirements, and mechanical nominal values for tensile testing, Charpy V-Notch testing, and drop weight testing. The plates can be normalized (L290N/X42N), quenched and tempered (L290Q/X42Q), or thermomechanically treated (L290M/X42M). The document defines maximum values for chemical composition analysis and minimum requirements for mechanical properties testing like elongation, absorbed energy, and shear fracture ratio.

*1) For t > 25 mm deviant analyses can be agreed upon with the customer
*2) If the C-content exceeds 0.18% (up to max. 0.20 %) the plate certificate has to be
submitted to the welding department before start of production
*3) For each reduction of the C-content per 0.01% an increase of the Mn-content by
0.05% up to 1.65 % max. is permissible
*4) If the C-content is > 0.12% the CE value of the product analysis applies
CE = [ C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15 ]
*5) If the C-content is </= 0.12% the Pcm value of the product analysis applies
Pcm = [ C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5xB ]
