Norinco uses 5150 Tool Grade Steel in the 1911s. Not for cost, they have unlimited 5150 due to the industry demands. China is the largest importer and consumer of steel in the world.
4140 alloy tool steel, aka CrMo steel. if US is the biggest consumer, China will be the 2nd. There is nothing fancy about 4140. It is good for machining, case hardening and the core provide the required toughness. I should not waste my time here.I am about to have a 1911 built for me, this is what it will begin as.

Please don't attempt to convince me that Norc uses a superior material than a North American, 4140 forging, to build their guns!
4140 alloy is the material that the likes of PGW, and many other high end gun manufactureres machine their receivers from, including Dlask, Wilson, Les Baer, Kimber, the list goes on and on. After machining parts from 4140 a part is heat treated to provide an engineered hardness range to match up to other component hardness ranges.
Something I am not convinced Norc do, perhaps someone can 'enlighten' me though.
Just because someone says/feels that a Norc frame is considered "tougher" than others, if that is the case, and I'm not saying it is, then what part do you think will begin to wear then as the gun is used? Perhaps maybe the slide rails?!
The matching of moving steel parts/components in a gun is a refined science. Something I'll leave to other 'quality' gun manufacturing companies............................Norc not being one of them!
I assume you have performed Rockwell or Brinell hardness tests to confirm the "toughness", or more correctly 'hardness', of a Norc frame and understand how hard the material should be, so the slide and frame rail wear evenly?
And probably the largest 1911 manufacturer as well
I don't know if 5150 Steel is the best grade for the 1911, but it sure works great! It was good enough for Bill Wilson who at some point in time, would only work on Colt, Springfield Armory and Norinco frame/slides...until he figured they spent too much on tooling to machine Norincos, darned Chinese steel was wearing out their expensive cutters faster than Colts and SAs.
If the guns design is so poor your worried about frame failures then it is time to move on to another style. If a frame cracks after 50,000 rounds that is one thing...with the ammo it took to get there you could have bought the gun 15x over and you can still reuse the internals on the one with the damaged frame.
You see, it sounds cool, but it's one of those internet myths.
Back then Wilson recommended or if You wish accepted Colt and SA for custom job.
He would also agreed to work on Norincos as only those 3 makers were producing forged slide and frame pistols back then.
Once the other makers caught up on the forged slide/frame thing, Norinco was dropped from the line.
Not because of the steel, just because other makers were putting better stuff on the market.
You still can build a custom gun on Norinco frame and slide with many gunsmith across the USA.
There are however better choices out there.
Good starter gun, but nothing more really.
It is actually the high grade of tool steel that is appealing to most americans. The Norc 1911 frame and slide is incredible hard and resilient. These make excellent bases for a custom 1911 build, and yes they will compete with the big dollar guns if you know what you are doing. I own a couple of Norcs and a few other hi end 1911s though I am no expert. If anyone who has any of these horrible guns, I am willing to give you scrap metal value.(Insert sarcasm here!) LOL!
some people like to buy a old rusty car and fix it up just for the fun of fixing/restoring it.
