ups!
the forum erased the russian letters

50? (it´s like a T with vertical line at the left Ucase ?)
45?

40X?A = 40X?A (it´s like an omega upper case ?)
50X?A = 50X?A

The following are the 2 best sources for cross-referencing steel grades:

Stahlschlüssel
http://www.asminternational.org/Template.cfm?Section=Bookstore&template=Ecommerce/ProductDisplay.cfm&ProductID=12214

Worldwide Guide to Equivalent Irons and Steels, 4th Edition
http://www.asminternational.org/Template.cfm?Section=Bookstore&template=Ecommerce/ProductDisplay.cfm&ProductID=11476

The following covers non-ferrous metals:

Worldwide Guide to Equivalent Nonferrous Alloys, 4th Edition
http://www.asminternational.org/Template.cfm?Section=ShopASM&NavMenuID=18&Template=Ecommerce/ProductDisplay.cfm&Productid=11845

All of them cross-reference Russian GOST standards to ASTM, SAE, DIN, etc.  The ASM books can be purchased as a set for a slightly reduced price.
