If I've got it right:

WHERE 
CAST(SUBSTRING(Description,3,CHARINDEX('K',Description)-3) AS INT)
BETWEEN 10 and 40

Assuming your comment to this answer the first position isn't fixed so in this case you should use PATINDEX() function in MSSQL:

WHERE 
    CAST(SUBSTRING(Description,
                    PATINDEX('%[0-9]%',Description), 
                    PATINDEX('%[0-9]K%',Description)-
                    PATINDEX('%[0-9]%',Description)+1)
         AS INT)
      BETWEEN 10 and 40

One of the simplest solution is as below,

Select 
  * 
FROM 
  Table1 
WHERE
  Description like '__10K%'
OR
  Description like '__20K%'
OR
  Description like '__30K%'
OR
  Description like '__40K%';

Try This:

SELECT t.Id,
       t.desp,
from
(
SELECT [Id]
      ,[Description] as desp
      ,SUBSTRING(SUBSTRING([Description],3,LEN([Description])),0, CHARINDEX('K',SUBSTRING([Description],3,LEN([Description])),0)) as rag      
  FROM [dbo].[testRange]
)t
where CONVERT(INT,t.rag) > 20 AND CONVERT(INT,t.rag) < 40
