More carbon. Stronger. Harder. Worse to weld.
SM limits carbon equivalent. SS is a shed steel.
E4316. Four thirty. All positions. Low hydrogen.
Steady arc. Gas. Slag. Clean. Alloy.
Low hydrogen. Three hundred to three fifty. One to two hours.
Thick minus thin over average. Three percent or it walks.
CheckDecode E4316. Name the dry heat. Measure coat thick and thin. Keep eccentricity under three percent. A damp low-hydrogen rod is a crack waiting.
