NOTE : 1. Grade A in the thickness over 12.5 mm the manganese content shall not be less than 2.5 times the carbon content.

2. For Grade B, when the silicon content is 0.15 per cent or more (killed steel) the minimum manganese content may be reduced be reduced to 0.60 percent.

3. For Grade B, C, D and E, the sum of carbon content plus 1/8th of the manganese content shall not exceed 0.40 per cent.

CHEMICAL COMPOSITIONNOTE : 1. When the steel is Al-killed Nitrogen content shall be limited to 0.01 % max.

When steel is not fully killed by Al. alone Nitrogen content shall be limited to 0.007 % max.

2. When Al. or combination of Al & Si is used for killing the requirements regarding Min, Si, content do not apply.

* In the case of thickness or diameter below 6 mm, the yield stress shall be assumed to be at least the same as that for thickness or diameter between 6 mm and 16 mm.

** As amended in January 1975.NOTE 1) When chromium is used as an alloying element in Fe 540 WHT steel. It is desirable that

the combined percentages of manganese and chromium should not exceed 20 per cent.

2) Copper maybe percent between 0.20 and 0.35 percent as mutually agreed upon between the supplier and the purchaser.

3) When the steel is silicon killed the product analysis shall show a minimum of 0.10 % silicon. When the steel is aluminium killed or killed with a combination of aluminium and silicon the requirement regarding minium silicon content does not apply.

* In the case of thickness or diameter below 6 mm, the yield stress shall be assumed to be at least the same as that for thickness or diameter between 6 mm and 28 mm.

** As amended in January 1975.NOTE 1) In case of Fe 570 - HT steel Phosporus higher than that specified above is allowed if it is

added deliverately as an alloying element.
