First try. O1 is general purpose oil-hardening steel that is a popular choice for knife makers to make knife blades. Buy your O1 Blade Steel online here! O1 Tool Steel Grade Shapes, Sizes, and Technical Information From Tool Steel Service Inc. O1 Tool Steel is a very popular and highly versatile oil-hardening cold-work tool steel.

An oversized diameter allows for finishing to your exact requirements. It's 1/4" thick, 1 1/2" wide and about 2 1/4" long. O1 has good abrasion resistance and sufficient toughness for a wide variety of tool and die applications.

O1 OIL HARDENING TOOL STEEL ANNEALING Heat slowly and uniformly to 1140°F; soak thoroughly and then allow to cool slowly in the furnace to below 1000ºF. During welding of soft annealed O1 tool steel, the steel should be preheated to 300 - 500°C (572-932°F), welded at same temperature and finally the stress should be relieved immediately.

The Cr-Mo alloy electrode is preferable for welding structural steel. Hardened for increased abrasion and impact resistance, these precision-ground rods have a tight diameter tolerance and are ready for turning in your lathe. O1 is general purpose oil-hardening steel that is a popular choice for knife makers to make knife blades. O1 is the most common grade of steel for precision ground flat stock. O1 offers excellent abrasion resistance, ease of machining, wear resistance, and toughness.

Steel is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. The bar has been ground to achieve the precise shape and size. An excellent question from Brian: My question relates to tool steel. I am about to purchase a Veritas shoulder plane and for the first time am faced with the choice between A2 and O1 steel. Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & more. Normal care in heat treatment gives good results in hardening and produces small dimensional changes.

I am about to purchase a Veritas shoulder plane and for the first time am faced with the choice between A2 and O1 steel. Drill rod can be machined to produce drill bits, taps, shafts, files, punches, and more. USA ASTM O1 Alloy tool steel and O1 Mechanical Properties, Chemical Element, Cross Reference, Datasheet. I've heard it said that it is a little trickier to forge than simpler steels.
Grade Summary: O1 Tool Steel is a general purpose oil-hardening tool and die steel. Tool steel holds a cutting edge, resists abrasion, and maintains its shape at elevated temperatures. I understand that A2 is the harder steel, which has the benefit of holding an edge longer and the detriment of being more difficult to sharpen. It must be hardened in oil, which can be done at relatively low temperatures for good dimensional stability.
