N&T

* It is important to note that this grade of steel may be susceptible to cracking in the heat-affected zone of welds during post-weld heat treatment (stress relief). Therefore, ISG Plate recommends that careful consideration be given to this phenomenon by competent welding engineers before stress relieving is applied to weldments of this grade. Also, it is not recommended for service at temperatures lower than -50°F or higher than 800°F. ** At the producer's option, silicon may be .40 Max. When silicon is .10 min., the carbon shall be .28 Max. Post-weld heat treatment may degrade heat-affected zone strength and toughness. Pretesting of specific welding and post-weld heat treating procedures is recommended to assure optimization of final property levels.

* It is important to note that this grade of steel may be susceptible to cracking in the heat-affected zone of welds during post-weld heat treatment (stress relief). Therefore, ISG Plate recommends that careful consideration be given to this phenomenon by competent welding engineers before stress relieving is applied to weldments of this grade. Also, it is not recommended for service at temperatures lower than -50°F or higher than 800°F. ** Unless otherwise specified by the purchaser and approved by ISG Plate. Post-weld heat treatment may degrade heat-affected zone strength and toughness. Pretesting of specific welding and post-weld heat treating procedures is recommended to assure optimization of final property levels.

* Except one tension test required per each plate as heat treated. ** See listing of all Bridge steel grades on page 44. Post-weld heat treatment may degrade heat-affected zone strength and toughness. Pretesting of specific welding and postweld heat treating procedures is recommended to assure optimization of final property levels. It is important to note that this grade of steel may be susceptible to cracking in the heat-affected zone of welds during postweld heat treatment (stress relief) or elevated temperature service. Also, post-weld heat treatment or elevated temperature service may degrade heat affected zone toughness. Therefore, ISG Plate recommends that careful consideration be given to these phenomena by competent welding engineers before application. Is available as non-Q&T (TMCP) refer to ISG Plate.
