AISI 304 stainless steel (X5CrNi18-10) is a conventional austenitic stainless steel with good resistance to atmospheric, organic and inorganic chemicals. This material is widely used due to its excellent intergranular corrosion resistance, good cold deformability, good deep drawability and weldability.

This steel is only hardened by cold rolling. The modulus of elasticity, E , has a value of approximately 21 0 MPa, which cannot be increased by heat treatment.
Stainless spring steels Strips are classified as austenitic stainless steel. Due to their good balance of mechanical properties, they are the most widely used type of steel. They can be used in a variety of environments without being plated to prevent rust. In addition, as it is also possible to increase their hardness by rolling, they can be used as spring parts.
In annealed and lightly rolled materials, they exhibit a large degree of elongation, and can withstand complex processing. Springs are used in plenty of applications in the present-day world. Even so, only a few people have a nodding acquaintance with the brass tracks of spring manufacturing and the different qualities needed for various functions. While coiling steel into a spiral of desired length and diameter is the primary and center-most stage of spring fabrication, other treatments during and after the procedure determine the quality of the product that reaches the consumer.
In the condition +C, strip shall be delivered with a bright surface (2H), or a rough, matt surface
The following information shall be supplied by the purchaser at the time of enquiry and order:
a) the quantity to be delivered;
The products shall be free from internal defects that could impair their application to a significant extent. Tests appropriate for an assessment of the internal characteristics may be agreed upon at the time of enquiry and order.
AISI 304 1.4306 (X2CrNi19-11) and 1.4307 (X2CrNi18-9) are ultra-low carbon versions of 1.4301. The purpose is to improve the corrosion resistance after welding and prevent carbide precipitation caused by stress relief for a long time.
Grade 304 is a standard "18/8" stainless. It is the most versatile and most widely used stainless steel available, even though a wide range of alternatives are available; and has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing. This means that this grade steel is dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications, it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 can be readily braked or roll-formed into a variety of components for applications in the industrial, architectural, and transportation fields. It also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%) metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.
Cold rolled narrow strip of thicknesses up to and including 3 mm in rolled widths fess than 600 mm made from the stainless steel grades. The steels are used in the conditions for the production of springs and spring parts that are exposed to corrosive effects and sometimes slightly increased temperatures.
Strip is usually supplied in coils. Thin strip may be wound on a supporting centre, made of steel, cardboard or other material, in order to avoid the collapse of the centre. Strip may also be supplied as a spool, in order to increase coil weight, whilst minimising coil outside diameter, in the latter case, any welds shall be clearly marked.
Alternatively, strip may be supplied in cut lengths. These may be in a box, or on a pallet, and perhaps strapped together in bundles.
Several coils, or bundles of cut lengths, may be assembled on a carrier.
Unless otherwise agreed at the time of enquiry and order, the choice of delivery form is left to the discretion of the manufacturer.
Unless otherwise agreed at the time of enquiry and order, cold-rolled strip for springs is delivered with the edges. By special agreement, strip can also be supplied with mill edges or with special edges, e.g. machined edges, deburred edges or edges dressed to produce a regular form, usually square or round.
