Carbon steel 75Ni8 1.5634 with 2% nickel
Used especially for the manufacture of band saw blades, 15N20 / 75Ni8 / 1.5634 steel is a carbon steel with properties similar to 1075 steel, but containing a significant proportion of nickel.

Highly valued in the manufacture of Damascus Steel:
It is either used alone to make a blade, or alloyed with another steel 1075, 1095, O2 etc, for the making of a Damascus of a good contrast after etching. Nickel provides a high contrasting power (shiny parts), that is why 15N20 / 75Ni8 / 1.5634 steel is perfect for Damascus forging.

75Ni8 1.5634 carbon steel for the manufacture of knives and swords
It is easy to sharpen and its toughness remains one of its main advantages. Nickel steel 15N20 / 75Ni8 / 1.5634 can be used for the manufacture of knives, but also for the manufacture of swords.

75Ni8 1.5634 Quenched Tempered Strip Decarburization
For silicon alloyed steels, decarburization shall not exceed 3% of the material thickness per side,for non silicon alloyed steels, decarburization shall not exceed 2% of the material thickness per side when measure data distance of 5mm from the stripe edge

Hardened and Tempered Steel Strip (also known as hardened and tempered High carbon steel strip or, hardened and tempered carbon spring steel strip) is the basic raw material from which many different components are made, substantially being spring-type applications ranging from clutch plate segments to washers, retractor springs and even to tree springs in riding saddles and traditional clock springs. These strip products are a specialty of the Company and considerable plant development has taken place in recent years to facilitate a very wide range of dimensions, mechanical properties and coil weights. Hardened and Tempered Steel Strip gauges of between 0.10mm and 2.00mm can be processed and, depending on the appropriate combination to suit the process equipment, strip widths of between 4.76mm to 240mm are produced. The facilities also allow up to 2000kg coils to be produced though most are well below this, being governed by a very approximate relationship of 100kg per 25mm of width.

Carbon steel 15N20 with 2% nickel, ideal for the manufacture of Damascus steel

Perhaps you know this steel by another name:
The 15N20 corresponds approximately to the following standards: AFNOR 75Ni8 - AISI L6 - Wnr 1.5634

The surface finish of Hardened and Tempered Steel Strip products is not too critical in general engineering applications where the normal blue-black (also known as blue-grey) oxidized finish from the heat treatment is satisfactory. By control of the atmospheres in the furnaces non-oxidised surfaces can also be produced, on a selected basis, and alternatively, steels can be satin or bright polished were needed, these finishes being as much for cosmetic reasons as for engineering purposes.

75Ni8 1.5634 Quenched Tempered Strip Surface finish
The surface finish of cold rolled narrow steel strip shall be bright as produced by rolling and annealing in a controlled atmosphere.
The surface finishes of quenched and tempered cold rolled strip are as follows:
1 grey/blue oxide finish:unpolished;
2 brigth tempered:unpolished
3 polished: obtained by fine grinding, abrasive brushing or other processes;
4 polished and coloured:blue or yellow colour obtained by oxidization by heat
treatment.

In the production of spring steel wire, a variety of specialized equipment is essential. Shot Peening Machine. Wire Drawing Machine. Phosphating Equipment. Annealing Furnace. Polishing Equipment. Wire Coiling Machine. End Grinding Machine. Tensile and Compression Testing Machine.

Our commitment to excellence and reliability has resulted in long-standing partnerships with some of the biggest names in the industry. Like MW Industries, NHK Spring, Scherdel, Sogefi, Mubea etc. We also have established partnerships with several prominent Chinese steel groups, like Baowusteel, Xinyusteel, Nanjinsteel, Shagang etc.

Our spring steel wire comes in various categories such as music wire, hard drawn wire, oil tempered wire, chrome silicon wire, chrome vanadium wire, stainless steel wire, nickel plated wire, phosphate coated wire, galvanized wire, and copper coated wire.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
