不锈钢成本高
一吨普通钢6700
不锈钢2-3万
除了成本高之外一点用都没有

好象礼品枪有的用。
一般不锈钢硬度不好，发粘。 不锈钢也有好多种型号的。 316L的硬度兴许够了。

不锈钢是强度很低的一种钢材， 最大的问题是很多不能热处理，如淬火，正火什么的，尤其是316L， 烧到1400度，水冷， 反而强度会软下来。 而且不锈钢很容易加工硬化，一下子就裂了。
不锈钢的种类多如牛毛，一些枪管都是用不锈钢做的，你说能不能用？
316L这类奥氏体不锈钢强度是不高，但也比多数铝合金强多了，铝都能用，钢更没问题了。更何况还有N多马氏体不锈钢。另外，含铜量高的一些的沉淀硬化不锈钢，强度非常高，比如17-4PH之类。

卡彭特技术公司的Project 7000 15Cr-5Ni 不锈钢被用来制作鲁格.454转轮枪的枪管，性能好还易加工，当然Custom 465 stainless 也是用的。另外这个Project 7000 的母合金据说就是AMS5659，成分都一样，只不过更精炼过了而已。
Firearms Industry
When firearms manufacturer, Sturm Ruger & Co., Inc., Southport, CT developed the world’s first six-shot revolver in a .454 Casull caliber – the Ruger® Super Redhawk® – it used Custom 465 stainless for the cylinder to withstand the enormous pressure generated when firing this powerful cartridge. Designers started with Ruger's proven, rugged .44 magnum platform, planning to modify it to withstand the approximately 62,000 psi pressure produced by the .454 Casull cartridge.
The highest chamber pressure produced by a typical .44 Magnum cartridge is about 42,000 psi. Since the diameter of the chambers in the cylinder had to increase in order to accommodate the larger .454 cartridge, the cross sections between the chambers were reduced in thickness. So Ruger was faced with a design that required a now thinner wall to withstand an essentially 50% higher pressure than in the original cylinder.
To determine whether a breakthrough six-shot .454 Casull revolver was possible, Ruger fabricated a cylinder from Custom 465 stainless, then fired hundreds of rounds at a proof stress of 92,000 psi, approximately 50% higher than the stress produced under standard .454 firing conditions. After this testing, the chambers exhibited no cracking, scratches or other signs of fatigue.
The alloy’s full range of properties were required to actualize this superb design – high tensile strength, notch tensile strength, fracture toughness and corrosion resistance. The clean microstructure produced via premium melting and the inherent good machinability of the iron-nickel martensite matrix provided additional advantages in material savings and manufacture.
Field Results
In one highly successful production application, Sturm Ruger & Co., Inc., Southport, CT, used Project 7000 15Cr-5Ni alloy as a replacement for the conventional 15Cr-Ni alloy for the barrel in its new Super Redhawk .454 Casull. This is one of the most powerful commercially available revolvers in the world.
Designers were concerned with the throat erosion that might occur when the big cartridge would exit the chamber and slam into the interior surface of the barrel. The conventional 15Cr-5Ni stainless steel used for the barrel initially met all the design requirements for strength and corrosion resistance but one. It was very difficult to machine.
It took Ruger 28 minutes to gun drill a 0.480" dia. hole in a 1¼" OD x 19" -long bar (later hammer-forged over a mandrel and cut into three 7½" -long gun barrels) at the slow rate of 0.71 IPM. After switching to the Project 7000 version of the 15Cr-5Ni alloy, Ruger was able to reduce its gun drilling cycle time by 20% while improving tool life significantly. With its excellent transverse mechanical properties, the replacement alloy was able to resist the every high stresses produced by the large cartridge.
