409 409L Hot rolled stainless steel Plate

What is the difference between 409/409L and 410/410s stainless steel

409,410 are all high-strength stainless steel, (including chromium) but the temperature resistance is generally only about 500-750. This type of steel has the lowest chromium content of all stainless steels and is therefore inexpensive, making it ideal for use in environments where there is no corrosion or slight corrosion and partial slight rust is allowed. The Type 409 stainless steel sheet was originally designed for use in automotive exhaust system silencers (external corrosion). 410L stainless steel is commonly used in containers, buses and long-distance large cars, and has recently been used as a frame for LCD monitors.

Difference between stainless steel cold rolled plate and hot rolled plate
(409 409L Hot Rolled Stainless Steel Plate)

Cold rolling: hot-rolled steel coil is used as raw material, and the scale is removed by pickling, followed by cold continuous rolling. The finished product is rolled hard roll. The cold work hardening caused by continuous cold deformation makes the hardness and hardness of the rolled hard roll rise and tough. Plastic indicators have fallen,

Therefore, the punching performance will deteriorate and can only be used for parts that are simply deformed. Rolled hard rolls can be used as raw materials for hot-dip galvanizing plants because the hot-dip galvanizing units are provided with an annealing line.

The hard roll weight is generally 6~13.5 tons, and the steel coil is at normal temperature.

The hot rolled pickled rolls are continuously rolled. The inner diameter is 610mm.

Product features: Because it has not been annealed, its hardness is very high (HRB is greater than 90), and the machining performance is extremely poor. Only a simple directional bending process of less than 90 degrees (perpendicular to the winding direction) can be performed.

To put it simply, cold rolling is processed and rolled on the basis of hot rolled coils, generally in the hot rolling— pickling—cold rolling process.

Hot rolling is based on slabs (mainly continuous casting billets), which are heated to form strips from roughing mills and finishing mills. The hot steel strip from the last rolling mill is cooled by laminar flow to a set temperature.

Rolled into a steel coil by a coiler, the cooled steel coil, after different finishing lines according to different needs of users (flat, straightening, crosscutting or slitting, inspection, weighing, packaging and marking) Etc.) to become a steel plate,

Flat roll and slitting steel strip products. To put it simply, a billet is finely rolled after being heated (that is, the red hot, hot steel block in the TV), and then trimmed and corrected to become a steel plate. This is called hot rolling.
