Filed: 2002-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a production method of steel belt for a stepless transmission which is made of metastable austenite stainless steel and constantly has a stable quality and shape. SOLUTION: When a strip material made by welding a metastable austenite stainless steel in a ring shape is wound round tension and return rolls, the strip material is sent through a gap between work rolls located between the tension and return rolls and is rolled to produce a steel belt for a stepless transmission, the rolling is performed controlling a material temperature variation ΔT( deg.C) generated during rolling to be within ±6.4 deg.C. The metastable austenite stainless steel plate with an Md(N) value defined by the following formula being 20-100 is preferably used. Md(N)=580-520C-2Si-16Mn-16 Cr-23Ni-300N-10Mo By controlling the material temperature variation ΔT( deg.C) generated during rolling to be within the prescribed range, the processing inductive martensite variation Δα' during rolling of a ring is controlled to be within 5 vol.%.
