Strip steel 12C27 (raw) 500x50x4mm

Sandvik 12C27 steel plate 4x50x500mm, not heat treated (green). Sandvik 12C27 is a very famous steel made specifically for use in the knife industry. The guide to steels says about it that it is a corrosion-resistant martensitic chromium knife steel of the Swedish company Sandvic AB (Sweden), produced since the 60s of the XX century, which has a low content of impurities - sulfur and phosphorus. In other words, Sandvik 12C27 is perhaps the most balanced knife steel that simultaneously has excellent sharpening characteristics (easy to sharpen - hard to dull, and it really is!), high strength and corrosion resistance. The density of Sandvik 12C27 steel is 7.7 g/cm3 and its chemical composition is as follows:

Chemical composition in % (nominal):

Carbon (C) - 0.60%

Chromium (Cr) - 13.5%

Molybdenum (Mo) -

Silicon (Si) = 0.40%

Manganese (Mn) - 0.40%

Sandvik 12C27 is one of the few steels specifically designed for knife making. The production technology of Sandvik 12C27 steel is constantly being improved, which leads to a constant improvement in quality indicators, an increase in density and purity, and an improvement in the fine microstructure of carbides. Therefore, today's Sandvik 12C27 steel is very different from the prototype 45 years ago.

Sandvik 12C27 has high toughness, excellent cutting retention under various mechanical loads and good corrosion resistance. All this makes Sandvik 12C27 the most recommended steel for the production of high-quality extra-class knives.

Sandvik 12C27 steel is hardenable from 54 to 61 HRC. However, most often it is used hardened to a hardness of 58-59 HRC.
