Description
X46Cr13 Round Bars / 1.4034 Round Bars
X46Cr13 Round Bars is a High Carbon Version 1.4021 Grade also known as 1.4034. It has good workability when hot, and potential to reach high hardness. This versions contains %0.46 carbon and this version can get hardness up to 52-54 HRC after heat threatment.
1.4034 can be heat threated. This version has a higher carbon then the other versions of 420 and high carbon decrease the corrosion resistance.
X46Cr13 is a martensitic grade of 420 stainless stainless. It is magnetic and hardenable with rust resistant properties. X46Cr13 stainless is characterised by having a 0.43-0.50 carbon, and 12.50 – 14.50% chromium content. This mix of analysis gives our X46Cr13 stainless sheet and sections an outstanding corrosion resistance and exceptional wear properties after heat treatment. Superior to 410 and 416 type stainlesses for most applications. X46Cr13 stainless steel has good ductility in the annealed condition, but is capable of achieving 57HRC after treatment. Optimal corrosion resistance is realised when X46Cr13 is surface ground and polished after hardening.

Applications for X46Cr13 :
Dental and surgical instruments cutlery pump shafts gear pinions, cams, various hand tools, straight edges, parts for firearms and scissors. Not recommended for high pressure vessels.
All types of utensils, table knives, scissors, spindles, pump & compressor structures, piston rods, roller bearings, springs, surgical tools, mirror sheen finished elements.
Corrosion resistance of X46CR13 :
Stainless steel 1.4034 has good corrosion resistance which is provided against both chloride-free and aggressive media (e.g. nitric acid) and against water and steam. The corrosion resistance can be increased by polishing in the quenched and tempered state.
Please note that chromium carbides form in the soft-annealed and highly tempered state, which has a negative effect on corrosion resistance. The material is not resistant to intergranular corrosion and in combination with salt (MaCl) and salt water (seawater) there is a risk of pitting corrosion. It is not resistant to sulphuric acid. This material is only slightly resistant to formic acid.
