They are mechanical abrasion resistant spirals formed by the combination of high hardness and toughness. It is used where there is no corrosion.

St52 gets a certain hardness as it works, so it is a surface wear used in places. St37 is softer than this material. St52 heat treatment gains hardness St37 does not harden. Single Segment Scerw Flight are formed in a single line and structure.

Stainless steel augers are ideal materials used for the food field. It is often used in food processing, water treatment and other chemical industries. It is a slippery material and does not hold the product it carries.
304 Quality: Generally enough for use and standard productions.
316 L: Corrosion and abrasion resistance is quite good.
316 TI: It is used in environments where the material is exposed to high temperatures between 550-800°C.
309-310: They are materials resistant
