Doubtful, My company is a major distributor of spring steel and Chinese spring steel is a disgrace compared to Canadian steel. This based on first hand experience. I think you may be referring to Japan steel because the Japanese do have good steel.
Thanks for the reply, 50calshooter. I love to be corrected when I post because I get to learn new things. Now I know that China makes lousy spring steel.
But, as Misanthropist says, they can also make very good steel. As I understand it, one of the reasons Norinco guns look so rough is that the metal is hard to work on. I have NO first hand experience in the steel industry, except for some machine shop work, and I'm relating only what I have read online. My first hand experience with Chinese steel is limited to owning a couple of Norks, a replica sword, a couple of pocket knives, and lots of their kitchenware. (Damn Chinese -- everything I buy seems to come from there!

) But the guns, the sword, and the knives are noticeably harder than their equivalents from other lands and all except the guns are very well finished.
Thirty to forty years ago I worked in the quality control laboratory of a major manufacturer. Several times Purchasing had us test Chinese raw materials (clays and resins, not metals). They were always terrible -- but they got steadily less bad every time we tested them. I believe they long ago passed into acceptability; that manufacturer now has plants in China. Similarly, all the Norinco threads in CGN talk about how the guns have always worked but have improved steadily in fit and finish. (Of course you already knew that.

) The huge variability in quality is easy to understand when you remember that China holds one fifth of all the people in the world.
If you have more information, please let me know. I look forward to hearing from you.
