2015-02-09 13:45:35 Origin： Remark：0 Click：
FV520B is A Precipitation Hardening Martensitic Stainless steel with an addition of Nb/Cu elements. FV520 Combines High Strength, hardness (up to HRC40), and corrosion resistance. Mechanical properties at RM can be optimized with final age treatment.
TECHNICAL DATASHEET - Grade EN FV520B & FV520
OFFICIAL TEST CERTIFICATE: issued by TUV - SGS - BV
MATERIAL CATEGORY: Precipitation hardening
DENSITY: 7.80kg/dm
MATERIAL SPECIFICATIONS: DIN EN 10088-1
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VD / VIM followed by electroslag refining (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black / bright in the annealed condition.
Final heat treatment - solution treatment / Aged treated.

HEAT TREATMENT PRACTICE
Heat treatment is only suitable for specific grades of stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.
