WHAT IS THE HARDNESS 303 STEEL
By ASTM A240: HRB < 96
7390 m/s
410 is a harder SS and it is readily harden-able as well! However, it has less corrosion resistance then 316.
Ferritic stainless steel are magnetic, containing no nickel and not hardened by heat treatment. For example 409 and 430 stainless steel Martensitic stainless steel are also magnetic and containing no nickel but hardened by heat treatment. For example 410 and 420 stainless steel

WHAT IS THE VALUE OF A TAURUS NEW IN THE BOX JUDGE WITH A 6 INCH BARREL, STAINLESS STEEL. .410 GAUGE CALIBER?
The SS 410 is basically martenstic stainless steel which are more susceptible to hydrogen diffusivities, result in embrittlement Thus, SS 316 have better corrosion resistance than SS 410 material
As current passes through steel, it heats up from resistive heating. As it heats up, it expands. A typical coefficient of thermal expansion for steel is 13x10-6 m/m K but the exact coefficient of thermal expansion of steel depends on the type of steel.

what is the price on snake chamer 410 shotgun serial number 49796 has not been shot and is stainless steel
Sporting Arms Mfg. Littlefield TX & their phone number has been disconnected The Snake Charmer in 410 & stainless steel only is being currently (2010) manufactured by EAA. You can find the at Ellett Bro or RSR if you are a dealer.
First of all, a stainless steel is a steel that has > 10.5% Chromium (Cr); this ensures development of a chrome-oxide that prevents further oxidation. The 300 series of stainless steels differs from the 400 series in that the 300 series has both Cr and Nickel (Ni) - the 400 series has only Cr. 304 stainless steel has 18% Cr & 8% Ni. 316 stainless steel has 16% Cr, 10% Ni, & 2% Molybdenum (Mo). I believe this added Mo increases corrosion protection from chrloride-induced corrosion.
Rossi makes a copy of the snake charmer in blue or stainless. Lots of Rossi dealers.
Fe (iron/) 410 means that the steel has a strength of 410 Newton per Square millimeter while applying a pulling force.
