HISTORY SS 41 AND SS 400 ARE THE FORM OF PRODUCTS ROLLED STEEL FOR GENERAL STRUCTURE BASE ON " JAPAN INDUSTRIAL STANDARD" ( JIS) G-3101. SS 41 WAS PRODUCED UNTIL END OF DECEMBER 1990 AND AFTER JANUARY 1ST, 1991 THE PRODUCT WAS CHANGED TO SS 400. ASTM A 36 IS THE CARBON STEEL MATERIAL IN THE FORM OF ROLLED STEEL FOR STRUCTURAL QUALITY FOR USED IN RIVETED, BOLTED, OR WELDED CONSTRUCTION OF BRIDGES AND BUILDINGS, AND FOR GENERAL STRUCTURAL PURPOSES BASE ON "AMERICAN STANDARD OF TESTING MATERIAL" STANDARD

MATERIAL SCOPE (5.1) ASTM A 283 Gr C consist of four grade of material (A,B,C, & D) of Carbon Steel Plate of Structural Quality for General Application ASTM A 36 covers Carbon Steel plate, shape, and bar of Structural Quality for use in riveted, bolted or welded construction of bridges and building and for General Structural purpose From material scope, scope, both ASTM A 36 and ASTM A 283 are the Carbon Steel Steel of Structural Quality for General Application 2.

The chemical composition between ASTM A36 and ASTM A 283 Gr C differ only on Mn content, The effect of Mn and other element to the weldability can be known by Carbon Equivalen (CE) calculation The formula CE = C + Si/24 + Mn/6 + Ni/40 + Cr/5 + Mo/4 + V/4 where the element in % weigth

ASTM A 283 Gr C CE = 0.24 + 0.4/24 + 0.9/6 + 0 + 0 + 0 + 0 = 0.406 % It seem that CE of A 283 Gr C is higher than ASTM A 36. Base on this A 283 Gr C is litte bit difficult to weld compare to A 36. Refering to ASME IX the weldability of material is classified in to P-Number. Both A 283 Gr C and A 36 is group in to the same P number 1. It mean that once we make the WPS/PQR with A-36, it also valid for A 283 Gr C. (5.3)
