Material for Value-Tec stainless steel probes

Order Value-Tec stainless steel probes

The material used for manufacturing the Value-Tec stainless steel probe handles and probe needles is a martensitic hardened stainless steel AISI 410

It is used for the following products:
#52-001070         Value-Tec VP1 probe with straight tip
#52-001071         Value-Tec VP2 probe with bend tip
#52-001072         Value-Tec VP3 probe with slight crurved tip
#52-001073         Value-Tec VP4 probe with bend hook tip
#52-001074         Value-Tec VP5 probe with curved hook tip
#52-001075         Value-Tec VP6 probe with sharp curved hook tip

General remarks:

• AISI 410 is a martensitic steel (DIN 1.4006, X12Cr13) which can be hardened by heat treatment
• Contains 11.5 – 213.5 wt% Chromium
• Magnetic, hardened stainless steel
• Can be hardened by heat treatment
• Properties can be varied by different heat treatments
• Good corrosion resistance to most solvents, moderate corrosion resistance to salts and weak acids
• Generally used where moderate corrosion resistance combined with high mechanical strength is required
• Typical applications include probes, spatulas, knives, tools and springs
