BS EN 10270-3:2001 ..Steel wire for mechanical springs. Stainless spring steel wire 
This standard includes information on three steel grades 1,4310 ( with a normal tensile strength (NS) and a high tensile strength (HS)) , 1,4401, and 1,4568.

A typical designation according to this standard would be “Spring Wire BS EN 10270-2 – 1.4310 – NS -3,60 Ni coated
Steel designation number 1,4310 with nominal strength level. Nominal dia 3,6mm . Nickel coated
This steel has a nominal tensile Rm = 1500 MPa

Music Wire
This is the most widely used of all spring materials for small springs because it is the toughest.   It has the highest strength tensile and can withstand higher stresses under repeated loading conditions than any other spring material.  It can be obtained in diameters from 0,12 to 3mm.  It has a usable temperature range from 0 to 120oC

Oil-tempered Wire.  Music wire will contract under heat, and can be plated.
This is a general purpose spring material used for spings where the cost of music wire is prohibitive and for sizes outside the range of music wire.  This material is not suitable for shock or impact loading.  This material is available in diameters from 3 to 12mm.   The temperature range for this material is 0 to 180 oC..Will not generally change dimensions under heat.   Can be plated.   Also available in square and rectangular sections.

Hard-drawn wire
This is the cheapest general purpose spring steel and is should only be used where life, accuracy and deflection are not too important.  This material is available in sizes 0,8mm to 12mm.  It has an operating range 0 to 120oC

Chrome Vanadium wire
This is the most popular alloy spring steel for improved stress, fatigue, long endurance life conditions as compared to high carbon steel materials.  This material is also suitable for impact and shock loading conditions.  Is available in annealed and tempered sizes from 0,8mm to 12mm.  It can be used for temperatures up to 220 oC.   Will not generally change dimensions under heat. Can be plated.

Chrome-silicon wire
This an excellent spring material for highly-stressed springs requiring long life and/or shock loading resistance.  It is available in diameters 0,8mm to 12mmm and can be used from temperatures up to 250oC.   Will not generally change dimensions under heat. Can be plated.

a Manganese may be ordered with restricted range, but with a minimum range of 0.20 %b For heavy wire diameter (above 8.5 mm) chromium may be added up to 0.30 % for proper through hardening.Piano wire – springs that are mounted indoors in a stable environment without damp or high temperatures. This spring wire is not rust-proof.Stainless steel spring wire – used e.g. for high temperatures, in damp environments and in the food industry.Pre-galvanised spring wire – if the spring is used outdoors or in damp environments, pre-galvanised wire is useful.Electro-galvanised spring wire – if the spring is to be shiny, a spring made of piano wire can be subsequently electro-galvanised. This surface is shiny and offers a limited degree of rust protection. Please note that the electro-galvanisation process can cause acid brittleness in the wire.Hastelloy and Inconel – if the spring is to be used in the offshore industry, an acid-proof, corrosion-resistant material is chosen. This might be Hastelloy or Inconel. Hastelloy and Inconel are more precious materials that are less commonly seen.

Temperatures – if the spring is , for example, subjected to very high temperatures, over +120 degrees, stainless steel spring wire is beneficial, as it can tolerate higher temperatures.Material
