#Norinco 1911 Code Key Below

With the generous funding he got from the Australian taxpayer for the doomed Norinco 1911, my shooting buddy purchased a Glock.Tanfoglio tiene un modelo basado en la 1911 pero es solo en 45 acp. Filter by Firearm: - Select a Make - 1911 AK-47 AR.Anyway, under the anti-gun 'Buy Back' scheme, the Federal Government bought the 1911 (A true 'government' model indeed) and then - along with thousands of other surrendered firearms - they destroyed it. But its an interesting AK pattern. Forged and milled steel major constructions, slide stop, thumb safety, grip safety, hammer half-cock safety, U-notch rear sight, blade front side, 3-white-dot sighting for rapid acquisition of target, curved back-strap grip, black plastic or rubber grip plates.Here is a copy of a post from a friend of mine who is an engineer in Ottawa that will give you some idea of the quality of the steel in Norincos.Norinco Type 86S is an assault rifle in Counter-Strike Online.

So now we get into the 5100 alloy Norinco 1911 in particular. Even softer steels can crack and be brittle, it's a matter of how the internal stresses are relieved, or not, by annealing and hardening processes, as well as upon carbon on other constituent elements found in the steel.The steel used in their weapons, however, is every bit as up to snuff as North American steel is. Hardness does not necessarily equate to brittleness, that is a function of heat treating and alloy.

Norinco 1911 Code Key Below

This is a discussion on Norinco M14 Serial Number Database - North America.In layman's terms, the more important characteristics to crafting firearms is the toughness of the steel and modulous of elasticity of the steel. In the serial number code key below. The stainless guns have their own quirks (like spalling problems, corrosion resistance benefits, etc.)Model 1911 Commercial & 1st Mod N. This gives great wear resistance and Also should mention, I'm comparing apples to apples, so only the CroMo Colt is being compared to the CroMo Norinco here. It hardens very well on the surface but maintains an adequately ductile core.

Those older guns were only spot-treated at high stress areas and today have a rather high incidence of slide cracking using full factory loads due to a number of factors, including metal fatigue, crack propagation, creep, etc. In WW1, the guns were not even given what we think of today as 'heat treating'. Colt does not use the same alloy today it used in WW2 and earlier. This does not mean they are more brittle - it means that the alloy used to Make the Norincos (5100 tool steel*) results in a much harder surface when heat treated than does the Colt alloy (4140 Ordnance grade tool steel*).*Although the exact alloy formulations are 'industrial secrets', destructive testing done in the USA by the DCM (circa 1997) determined that Colt uses 4140 and the Chinese formulation used in 1911's and M14S receivers is an exact match to AISI 5100 series steel.Perhaps this is the time to mention something else about Colts. Comparing Rockwell hardnesses really won't tell you much, but as a general observation, on average the Norincos are at least 30% harder on the surface than most other 1911's, including the Colt.

The Chinese are as advanced as we are in Steel production. And the resulting pearlitic and/or martensitic grain structures, but frankly, unless you work in a foundry or have a mechanical engineering degree and understanding of materials science, it would be way too far over everyone's head so I'll try to keep this explanation understandable for the average fellowNow for a short note on Chinese steel 'quality'. A good thing, but at the same time - these babies should be collected and admired more than turned into a range marathon pistol!I could get further into heat treating, including annealing, case hardening, gas carburizing, cyanide dips, etc. That being said, the steel is very ductile and in the event of failure, it should just bend and crack - not fracture like a grenade.

It really does have better end-product properties than 4140 steel does, and it's also easier to smelt at the steel mill and forges beautifully. This is probably why so few smiths will do Novak cuts to a Norinco slide - they probably only have HSS tooling!5100 alloy is, most probably, the alloy most manufacturers WOULD chose to build receivers if tool bits were cheap and labor costs were low. Most smiths have to buy carbide mill bits to work the steel, and even then there's a very high tool wear rate. On a finished gun the only way you're going to cut it with HSS mill bits is if you spot-anneal the steel with a torch first. Norinco, I suspect, machines their parts with carbide cutters prior to heat treating. The one achilles heel to 5100 series alloys is that they are notoriously hard to machine.

But frankly, trashing the steel is a bigotted and unfounded arguement based on ignorance and reliance on the Go-USA writings of most internet experts 'I hope this gives you a better perspective of the Norinco 1911. This makes 5100 steel actually cheaper for them to use b/c of the lower costs associated with making the steel stock.All this to say, you can complain about the design, fit, finish, and economics of a Norinco 1911. The Chinese are fortunate in that they make many of the tool steel bits on the market (cheap supply) and lobor costs are very low. 4140 is an entirely adequate steel for use in guns, it also wears tools at a much slower rate and can still be machined easily after hardening.
