ฝังหัวอยู่นานว่า S30V นี่เป็นเหล็กสุดๆตัวหนึ่ง
มีดอย่าง Chris Reeve Strider กระทั่ง Spyderco รุ่นสูงหน่อยก็ใช้ตัวนี้
เผลอไปหน่อย อ้าว CRK ขยับไป S35VN ซะแล้ว
มันต่างกันตรงนี้ครับ Chris Reeve เจ้าสำนักบอกไว้แบบนี้
CPM S30V and S35VN Stainless Steels were developed by Crucible Steel in Syracuse, New York. During 2001/2002, Chris worked with Crucible pursuing the challenge of creating a new blade steel specifically for the knife industry that was tough, corrosion resistant and readily workable. The product of their efforts was S30V, alloyed to accommodate these specific capabilities and manufactured to ensure clean, uniform steel.
Unlike traditionally cast and rolled steel, CPM (Crucible Powder Metallurgy) is produced in a process that reduces molten alloy components to minute balls - or powder - which results in every grain comprising the exact composition of alloy elements. The powder is compressed under significant force to a homogenous, solid state and the steel is rolled to required stock size.
A small yet significant advance was made when S35VN was introduced in 2009. The addition of Niobium to the alloy results in finer grain structure which gives more toughness. This means slightly better edge retention, shock absorbency and corrosion resistance.
For the technically minded, the major alloy components of S35VN are:
Carbon (C) 1.4%
Chromium (Cr) 14.00%
Vanadium (V) 3.00%
Molybdenum (Mo) 2.00%
Niobium (Nb) 0.5%
