BS 1387 is UK Standard and ANSI/ASTM are American Standards; both deals in the specifications of Steel or Alloy pipes sizes, BORE, WALL THICKNESS, chemical composition, and manufacturing process.Both are standard in manufacturing and material process specifications.For example;ASTM A 53-90b Carbon-Steel Pipes, Welded (F & E Types) or SEAMLESS (S Type) Grade A & BBS 1387 Medium (Class B) can be the equivalent etc...etc...
Carburize (Materials) BS 4360 43C is a structural grade like ASTM A 36 but with guranteed charpy properties:C .19 max, Si .5 max, Mn 1.5 maxUTS 62,400 psiYield Strength depends on thickness but up to 1.5-inch would be 35,000 psiCharpy impact tested at 0 degrees C (-32 Degrees F)minimum average impact toughness 27 J (20 ft lb)
The equivalent to BS 4360 Grade 43A in Indian Standard is IS 2062. Both standards specify general construction steel grades with similar chemical composition and mechanical properties.
