When a podger ratchet is marked with words like Cr-V, it may mean nothing to do with Cr-V, or only the socket is Cr-V.
Why is that?
Cr-V is symbol of chromium-vanadium steel, which is steel alloy incorporating carbon, manganese, silicon, chromium and vanadium. Chromium and vanadium both make the steel more suitable for hardening, chromium also helps resist abrasion, oxidation, and corrosion. While carbon steel is composed of iron and 0.12 – 2.00 percent carbon. So is easy to tell that Cr-V is better than carbon steel at many aspects.
So you may thought it was a misleading or even cheating when a podger ratchet is carbon steel but marked Cr-V, but it happens in China as fierce competitions in the market, manufacturers try to level manufacturing cost down from materials at the very beginning, this mostly happends in those manufacturers with price as orientation, but please do not feel frustrated as even carbon steel socket will be strong enough for the strength and durability that podger ratchets are designed for.
So how to tell podger ratchets is made with Cr-V socket or Carbon Steel Socket?
Following picture will tell you all.
Left socket is Cr-V type with uniform 12 points which gives you third-dimensional sense, while right socket carbon steel type is bit of rough at surface texture and less dimensional which may cause slipping or wearing.
We choose Cr-V socket for popular sized podger ratchets, for example 19x22mm and 19x21mm. Other less requested sizes like 24x30mm or 32x36mm we choose carbon steel as consideration to economic aspect, but after qualified quenched and tempered process, carbon steel socket can also provides excellent working performance.
If you look close, you may find there is step between two sides of left socket, while right carbon steel socket is go-through which can be a advantage when you use it to long bolts.
In a words what suits you better is the best.
