GIN-1 vs ATS-55?

[Jeff/1911]

Sorry to repeat the question I just posted in the "Matte finish stainless Police model" thread, but I thought it might be better posed this way. So here goes:



Is there a benefit to GIN-1 over ATS-55 in the Police model? Should I be looking for one of the past GIN-1 versions instead of buying the current production ATS-55 model? I will be choosing a serrated blade in this knife, in case that makes any difference. Jeff/1911.

Puh, this is a very tough issue, Jeff/1911. There is a difference. This question is so complicated that it would take hours to work it through. However, here are the <i>“main players” </i> and their impact on steels as read from Spyderco&#180;s dealers catalog:

<b>Carbon (C) </b>
1. Increases edge retention and raises tensile strength
2. Increases hardness and improves resistance to wear and abrasion
<b>Chromium (CR) </b>
1. Increases hardness, tensile strength and toughness
2. Provides resistance to wear and corrosion
<b>Cobalt (CO) </b>
1. Increases strength and hardness and permits quenching in higher temperatures
2. Intensifies the individual effects of other elements in more complex steels
<b>Copper (CU) </b>
1. Increases corrosion resistance
<b>Manganese (MN) </b>
1. Increases hardenability, wear resistance and tensile strength
2. De-oxidizes and de-gasifies to remove oxygen from molten metal
3. In larger quantities, increases hardness and brittleness
<b>Molybdenum (MO) </b>
1. Increases strength, hardness, hardenability, and toughness
2. Improves machinability and resistance to corrosion
<b>Nickel (NI) </b>
1. Adds strength and toughness
<b>Phosphorous (P) </b>
1. Improves strength, machinability and hardness
2. Creates brittleness in high concentrations
<b>Silicon (SI) </b>
1. Increases strength
2. De-oxidizes and de-gasifies to remove oxygen from molten metal
<b>Sulphur (S) </b>
1. Improves machinability when used in minute quantities
<b>Tungsten (W) </b>
1. Adds strength, toughness and improves hardenability
<b>Vanadium (V) </b>
1. Increases strength, wear resistance and toughness

Spyderholic - I received your email but I can't call you long distance from work. Thanks anyway.

DePaul - Thank you VERY much for the indepth response. I'll study the charts.

Jeff/1911.
