Hugh-Candoit (ENG) Posted June 7, 2009 Report Share Posted June 7, 2009 Trust me not to read the whole thing. Thought they were used for Chubb type locks but dont know where I picked this up from Link to comment Share on other sites More sharing options...
kobblers Posted June 7, 2009 Author Report Share Posted June 7, 2009 Mmm, I've often wondered why our key suppliers would manufacture steel blank alternatives for locks such as Chubb if indeed it is true that they wear the lock quicker Rick.

Russell Posted June 9, 2009 Report Share Posted June 9, 2009 B440 blanks are not steel, they are alloy!! Link to comment Share on other sites More sharing options...
redcap Posted June 9, 2009 Report Share Posted June 9, 2009 Ehhhhh.... I hate to be pedantic... but steel IS an alloy!!!! .....or should I say steel is a 'family name' given to many different alloys based on iron (mixed with carbon and other elements).... some of which are softer than other alloys used to make keys (although it also depends on the final heat treatment the steel is given)! ....these things are never straightforward.... are they!
